海外TECH DEV Community Strive for short-lived synchronous communication https://dev.to/bohdanstupak1/strive-for-short-lived-synchronous-communication-a74 Strive for short lived synchronous communicationWhen interacting with a service asynchronous communication often is a preferred way Enterprise integration patterns book puts it that way which also might be a TL DR for the rest of the article With synchronous communication the caller must wait for the receiver to finish processing the call before the caller can receive the result and continue In this way the caller can only make calls as fast as the receiver can perform them On the other hand asynchronous communication allows the sender to batch requests to the receiver at its own pace and for the receiver to consume the requests at its own different pace This allows both applications to run at maximum throughput and not waste time waiting on each other at least until the receiver runs out of messages to process However there might be scenarios when synchronous communication is unavoidable Let s have a look at the example Communication between servicesLet s imagine we have a system that uploads and processes files It consists of a legacy module upon which we have no control This module takes a file from the file system uploads it to the given endpoint via HTTP and if the upload is successful it uploads a supplementary metadata file Since we have no control over the legacy module we have no other option than to stick with synchronous communication Once the file is uploaded to our system we perform numerous processing activities which consume a considerable amount of time We can summarize the current state of affairs with the following diagram Extracting long running task into separate jobAs always there s nothing wrong with this design unless you apply some scale to it But once the requirement to upload a big amount of files arrived it appears evident that the bottleneck is the legacy module waits every time until our code is done saving and processing the file before it can upload the additional file So in order to fulfill the requirement we need to reduce interaction time Then you start noticing how wasteful is to wait until processing is done on every HTTP request The remedy is to return the response early and perform processing in the background Here asynchronous communication is denoted with the dashed arrow Once we persist the file we send a message that the file is saved to the processor module To enable this we might employ AMQP implementation of our taste Since a message is asynchronous we don t have to wait for processor response and are able to return the response to our legacy uploader component way earlier Notice that both components communicate inside a single process There s the reason for this which I ll cover in the next section Scaling solution horizontallyUp to this point some of the readers might bear a question why leave both components inside a single service when you could separate them While microservices were a hot topic couple of years ago nowadays more organizations start realizing that doing microservices correctly is hard It requires certain engineering capabilities distributed logging failure recovery as well organizational capabilities code ownership separation maintaining up to date contracts between services robust deployment strategy All this should serve as a precaution for those who use microservices solely as a tool to split their codebase into more manageable pieces And this is why I ve decided to stick with inter process communication as the default architectural style Still there might be cases when due to high load you have to scale the solution to endure even bigger loads So the natural solution would be to handle file upload in parallel However parallelizing process on a single server instance has its own limits so eventually you ll come up with deploying service on multiple services horizontal scaling In such a case the IO intensive part that persists files to the database might benefit from horizontal scaling while processor part may benefit from vertical scaling say adding more powerful processor to perform computation intensive logic The ability to scale part of the system independently is one of the key reasons to use the microservices architectural style Another one is inverse Conway maneuver but it is beyond the scope of the article In such a case both parts of the system are deployed independently and are communicating via message queue as on the figure below Reducing HTTP request durationAnother area of interest is customer facing UI applications Numerous studies reveal how an increase in page load time leads to customer dissatisfaction Since HTTP call duration is an integral part of page load time naturally we want to reduce it too Let s have a look at the following hypothetical code responsible for registering users in the application public async Task lt IActionResult gt FlushTemporary CancellationToken token if validator IsValid user await repository SaveUser user token await mailingService SendConfirmationEmail user token return Ok While the code above leverages a feature named asynchronous programming model in fact from the callers perspective it s synchronous since the caller needs to wait until user is persisted in DB and confirmation email is sent Needless to say that this leads to an extra wait for a customer during a registration step Here again as in the example above we should extract confirmation email into the background job that will be executed after the registration step ConclusionSynchronous communication introduces wait times that might be redundant during inter system communication or in customer facing applications It s crucial to understand which part of synchronous communication is unavoidable and which part might be done later For the latter part background processors are a neat trick to handle the issue 2021-11-19 14:51:16

海外TECH DEV Community Flask CRUD API https://dev.to/tinystacks/flask-crud-api-3pl2 Flask CRUD APIWelcome back on the Docker and AWS series by TinyStacksIn this Article we will create a simple CRUD API using a Flask Application Docker PostgresVideo Version Steps Create a folderCreate requirements txtCreate app loc Create DockerfileCreate docker compose ymlRun databaseCheck databaseRun python appCheck that the table has been createdTest endpoints Postman Test Get All endpointCreate a record x Get a recordUpdate recordDelete record Create folder and step into itYou can create a folder in anyway that you prefer If you use a terminal you can type mkdir flask crud apiThen step into the folder cd flask crud apiThen open this folder with your favorite IDE If you use Visual Studio Code you can type code Now we re ready to get started coding our Flask Crud API application with the help of GitHub Copilot Create requirements txtFirst of all we need to define the dependent Python libraries for our application The standard method in Python is to create a requirements txt file and list our dependencies there So create this file called requirements txt If you have the Material Icon Theme it will show a nice little Python icon It s a nice to spot typos Then we can type the dependencies for our project flaskpsycopg binaryFlask SQLAlchemyThose dependencies are flask The Python Frameworkpsycopg binary To create the connection with the Postgres DatabaseFlask SQLAlchemy Help generate SQL queries without writing them manually Create app loc At the root level create a file called app py We will write our crud API app in about lines of code Let s specify the libraries we ll use from flask import Flask request jsonifyfrom flask sqlalchemy import SQLAlchemyimport osNext define the Flask app and how to run it app Flask name if name main app run debug True Define an environment variable as a string and initialize the SQLAlchemy instance to handle the Postgres database app config SQLALCHEMY DATABASE URI os environ get DATABASE URL db SQLAlchemy app Now let s define our data model We ll create a class named Item with just title and content as properties We ll also add an auto incremental Integer named id This will act as the primary key for our table class Item db Model id db Column db Integer primary key True title db Column db String unique True nullable False content db Column db String unique True nullable False def init self title content self title title self content contentNow a little bit of magic with this line we let SQLAlchemy to synchronize with the Postgres database This will create our databasetable automatically for us db create all Define REST endpointsNow we need to implement our CRUD endpoints CRUD stands for CREATEREADUPDATEDELETEThese are the basic functions of every application To retrieve a singleitem we define this function app route items lt id gt methods GET def get item id item Item query get id del item dict sa instance state return jsonify item dict To get all the items in the database we define this function app route items methods GET def get items items for item in db session query Item all del item dict sa instance state items append item dict return jsonify items To create a new item app route items methods POST def create item body request get json db session add Item body title body content db session commit return item created To update an existing item app route items lt id gt methods PUT def update item id body request get json db session query Item filter by id id update dict title body title content body content db session commit return item updated To delete an existing item app route items lt id gt methods DELETE def delete item id db session query Item filter by id id delete db session commit return item deleted That s it and in less than lines of coding included new lines Create DockerfileA Dockerfile is a text file to define a set of commands to create an image Starting from this image we will run our python containersLet s create a file called Dockerfile capital D no extension We could create of course a file with a different name But this is the default one that Docker uses If we use it we don t have to specify a name for the file when we build our Docker container image This is the final file FROM python slim busterCOPY requirements txt RUN pip install r requirements txtCOPY EXPOSE CMD flask run host port Let s explain briefly what s going on here FROM Set the baseImage to use for subsequent instructions FROM must be the first instruction in a Dockerfile COPY Copy files or folders from source to the dest path in the image s filesystem The first COPY copies the requirements txt file inside the filesystem of the image the second one copies everything else RUN Execute any commands on top of the current image as a new layer and commit the results In this case we are runningpip to install the Python libraries we need EXPOSE Informs Docker of the port we will use at runtime PRO tip this line is not really needed It makes the intent of the Dockerfile clear and facilitates the translation to the docker compose yml file CMD Provide defaults for an executing container If an executable is not specified then ENTRYPOINT must be specified as well There can only be one CMD instruction in a Dockerfile Create docker compose ymlNow that we have created the Dockerfile let s create the docker compose yml file to make our life easier This is the final file ymlversion services pythonapp container name pythonapp image pythonapp build ports environment DATABASE URL postgresql postgres postgres db postgres depends on dbdb container name db image postgres ports environment POSTGRES PASSWORD postgres POSTGRES USER postgres POSTGRES DB postgres volumes pgdata var lib postgresql datavolumes pgdata Let s explain what s happening line by line version is the current version of the docker compose yml file services The top level entry of our docker compose yml file The services are basically the containers pythonapp The Python application we just wrotecontainer name Defines a custom name for our application It s the equivalent of using the name option at the command line when we run docker run image Rhe image for this service container Here we are defining a custom name just to use it locally If we want to push our containerto a public or private registry a place to store Docker Images e g Docker hub we need to change the tag of the image basically the name We don t need to do that now build We need this option if we are using our custom image and not an existing one The dot after the semicolon is the path of the Dockerfile and it means here is where I mrunning the docker compose yml file Please note that the docker compose yml file and the Dockerfile are at the same level ports A list of ports we want to expose to the outside A good practice is to make the content a quoted string environment Key value pairs Here we use them to define our custom URL to connect to the Postgres database depends on Express dependency between services Service dependencies cause the following behaviors docker compose up starts services in dependency order In the following example db and redis are started before web docker compose up automatically includes a service s dependencies In the example below docker compose up web also creates and starts dband redis docker compose stop stops services in dependency order In the following example web is stopped before db and redis db Service for the Postgres database container name The default name for this service also called dbimage postgres We will not use our custom image in this case but an existing one the one the Postgres team has created and pushed for us on Docker Hub ports A list of ports we want to expose to the outside A good practice is to wrap this content in a quoted string environment Here we define three environment variables for the Postgres service The keys are not arbitrary but are the ones defined in the official Postgres image We can of course define the values of these environment variables this is why the Postgres team has given them to us to use them volumes Here we use a named volume called pgdata the part before the is the name of the volume and the part on the right of the is the destination pathAt the end of the file we define the actual volume named pgdata Run the database service locallyTo run the database service locally we can type bashdocker compose up d dbthe d option stands for detached to leave out terminal available after running this container You can check the status of the running container by typing docker ps Check the databaseTo step inside the Postgres container we will use different approaches First approach directly from the Command linedocker exec it db psql U postgresBut if we type dtWe will see this did not find any relationsThis is correct because we haven t run our Python container yet To exit the psql process type exitOr alternatively just q Run Python appTo run your Python application type docker compose up build pythonappThe build option is to build your application before running it It s not useful the first time you run this command because Docker is going to build the image anyway It becomes useful after you run docker compose up multiple times and you ve made some changes on your app Note If you build an image using the same tag name the previous image will become a so called dangling image with lt none gt lt none gt as the repository and tag To remove them you can type docker image prune and then y to confirm if you see something like this you have successfully launched your Python Flask application Now you can once again check the running containers docker ps a Side note don t mind the created value it s just me removing stopping the containers for demo purposes You should see them both running with a status of some minutes ago Check the table has been createdIf you step again inside the Postgres container now using the command docker exec it db psql U postgresand you type dtyou will see the table has been created automatically without calling any endpoint This was possible because of the line around on the app py file pythondb create all Test endpoints using Postman Let s test this simple application We will use Postman but you can use any REST API testing tool that you prefer Get AllLet s get all the items Create one x Now let s create some new itemsApologies for my lack of imagination Get oneTo get a single item you can just make a GET request at the endpoint item lt id gt where lt id gt is the unique ID of the item that you previously created For example to get the item with id Please note that we are not handling errors correctly in this example If that id doesn t exist we ll get an error directly from the application and we won t show an error message to the end user Update oneTo update an existing item you can make a PUT request using the lt id gt of the item in the body Delete oneFinally we can delete an existing item from the database We can make a DELETE request and appending an existing lt id gt at the end of the url If you get all the items again this will be the result Test the final status using the promptYou can test the final status also directly on the db docker exec it db psql U postgresand then run the psql command don t forget the final select from item All the code is available at this url Video Version Video offered by TinyStacks 2021-11-19 14:39:17

海外TECH DEV Community How to make a profit from an online marketplace. Top 6 marketplace monetization models https://dev.to/arateg/how-to-make-a-profit-from-an-online-marketplace-top-6-marketplace-monetization-models-13kk How to make a profit from an online marketplace Top marketplace monetization modelsThe success of online marketplace platforms depends on various factors that include stakeholder satisfaction industry competition delivered functionality and promotion strategy Marketplace monetization is a key aspect that a company has to consider before implementing a software project When managing a marketplace application an organization generally does not produce supply or sell any goods The primary objective is to bring together vendors and consumers for value exchange As a result marketplace owners rely on the volume of sales generated via the system and the number of users Therefore by choosing a marketplace monetization model properly you will be able to generate higher profit while improving the audience s engagement In this article our software experts describe the main marketplace revenue strategies for you to do benchmarking and find the best one for your project Have a look Top marketplace monetization models to consider Registration feesA registration fee also known as a sign up fee is a popular marketplace business model that requires a flat payment from vendors for joining the platform This way sellers have to pay only once and then operate freely on a marketplace Benefits of using sign up fees It is much easier to adopt this strategy in comparison with other practices For example when charging a commission a percentage of every transaction amount has to be automatically calculated and transferred to marketplace owners while the remaining sum has to be sent to merchants By employing this strategy the revenue will not depend on the volume of sales Drawbacks of this marketplace monetization model It can be quite challenging to assure sellers to make a payment before registration If you manage to attract the majority of vendors operating on the market you will have to incorporate other revenue models to have a steady source of income When bringing the registration fees model into action it is crucial to Conduct competitor analysis Before launching a software solution an organization should research conditions suggested by similar marketplaces to come up with more favorable terms With lower fees it will be much easier to draw the attention of merchants which is vital for new market players Create a catching selling proposition To engage vendors and earn a profit it is important to convince them to register by describing the advantages Offer a bonus for signing up This is a great way to draw the attention of service providers especially when you have just released a marketplace It is worth remarking that typically digital marketplace platforms do not require customers to pay sign up fees as they are not likely to pay before ordering products or services when there are so many other free solutions Example with ClickBankEstablished in ClickBank is a worldwide online e commerce and affiliate marketplace delivering either physical or digital products At the moment the system is used by over six million customers across the globe To start using the platform service providers have to pay an activation fee of In addition ClickBank also withdraws a commission for payment processing Transaction commissionThe commission is among the most widespread marketplace monetization models used by globally recognized companies such as Amazon and Uber Eats With this strategy vendors and consumers can register on a marketplace application for free In this case the revenue depends on the number of transactions carried out through the system as well as their amount if a fee is not fixed Benefits of charging commission As marketplace operators receive a percentage of each transaction it is easier for them to maintain the level of income Vendors have the possibility to try out system functionality prior to making any payments As a consequence the credibility of an online platform increases Drawbacks of this marketplace monetization model It is more difficult to implement this strategy in comparison with some other options such as flat sign up payments When you have just launched a marketplace app it may take a while to attract sellers and buyers As long as a small fee is withdrawn from each successful payment this marketplace monetization model generally showcases the best results in the long run To make this business model work companies should Calculate what fee has to be withdrawn for generating sufficient profit Before setting up the amount of a transaction fee it is also advisable to analyze the terms provided by competitors Help suppliers maximize sales by delivering components necessary to automate business operations and ensure a seamless experience For instance a company can integrate a digital marketplace platform with systems for order and shipping management With functionality like one click ordering voice payments and product comparison vendors will be able to significantly raise the conversion rate Example with AirbnbAirbnb is a world famous online lodging marketplace operating according to a peer to peer model To improve the audience s satisfaction Airbnb comes up with more beneficial conditions in contrast with many other marketplaces The platform demands a relatively small commission for carrying out each guest host transaction splitting it between two parties While customers are charged a fee ranging between vendors have to pay a fee of Explore how to build a marketplace like Airbnb involving project cost and timeline As a comparison Booking com requires an average commission of which is paid by accommodation owners only This fee can vary depending on property type and location It is worth noting that a transaction fee in on demand service marketplaces like Uber Eats and Postmates hovers around SubscriptionWith a subscription monetization model vendors have to make regular payments in order to use a marketplace platform or access some bonuses To make this strategy work it is crucial to keep merchants engaged The key benefits of a paid subscription A company receives a steady source of income while sellers do not have to make a large payment before they run a business on the platform This practice is perfectly suited for the long run Drawbacks of this marketplace monetization model A high churn rate may become the biggest challenge Subscription may not fit some sectors due to their specifics For example operating in the foodservice industry Uber Eats does not apply a paid subscription to avoid the risk of encountering restaurant churn When using this strategy it is important to Provide a free trial By allowing businesses to try out marketplace functionality you will manage to increase the number of registrations and subscriptions Continue reading 2021-11-19

different departments of an organization collaborate What is ERP integration with eCommerce Platforms ERP integration with eCommerce platforms is the process of establishing integration between an ERP software and eCommerce platforms like Magento Shopify WooCommerce etc Such integration facilitates a seamless transfer of data from the eCommerce platform to the ERP software The question however is why does an ERP software need to integrate with eCommerce platforms The answer is simple ERP software looks after all the crucial processes in an eCommerce business These processes include monitoring inventory processing orders optimizing shipping process generating custom reports andtracking multiple application workflows in real time All these processes need data related to customers orders products and categories Such data is stored in the merchants online stores which are built on the above mentioned eCommerce platforms Therefore ERP integration with eCommerce platforms is necessary if the ERP software needs access to this data When an ERP integrates with the eCommerce platform it can retrieve and manage an online store s data through the platforms APIs Moreover there are several benefits associated with ERP integration with multiple eCommerce platforms ERP eCommerce integration opens new business opportunities The eCommerce platforms you connect with have multiple online stores built on them apart from your clients These online store owners can be your future clients when they get to know the functionalities of your ERP software When the store owners turn into your

How to Develop an eCommerce ERP Integration There are two ways to develop an eCommerce ERP integration in house integration development and using third party integration development services While in house integration development can cost you a significant amount of time money and resources employing a third party service to develop integrations is your most feasible option With third party service providers like APICart you can easily develop ERP integration with multiple eCommerce platforms APICart is a unified API that allows SaaS solutions like ERP to integrate with more than eCommerce platforms at once As a result it saves the vendors a lot of time and money they would otherwise have invested in establishing individual manual integrations APICart provides you with more than API methods to retrieve and manage data from the eCommerce platforms These methods allow you to seamlessly edit delete modify and update data in the online stores Moreover APICart also looks after the maintenance and upgrades required by integrations once they are developed If you look into in house development you would also have to bear the cost of maintenance and updates equivalent to developing new integrations eCommerce platforms keep rolling out new versions of their API and you will need to update your integrations every time there s a new release If you choose manual integrations these updates and maintenance might cost you a fortune considering the salary you will pay to the developers and the infrastructure you will deploy APICart can save you from all these pain points with its unified API You need to connect your ERP software with APICart and it will automatically connect your software with all the eCommerce platforms of your choice 2021-11-19 14:23:27
