海外TECH	DEV Community	Approaches in Cloud Development Ergonomics	https://dev.to/eyalb/approaches-in-cloud-development-ergonomics-5967	Approaches in Cloud Development ErgonomicsThe advent of microservice architectures and cloud native has taken some pretty severe tolls on developer ergonomics It feels as if the tools cloud developers have at their disposal haven t evolved fast enough to keep up with the rapid progress in infrastructure and this tool debt is readily apparent in the day to day of the modern developer The clearest example of this is that it s now really hard to just run your application Not the one microservice you re currently working on but your actual entire application which you ultimately deploy to the cloud and serves your customers You used to be able to fire up your monolith right there on your laptop from within your IDE crash change some code run it again but architectures today have become resource intensive reliant on third party services and mostly just plain convoluted to the point where local execution is no longer a viable option When we talk about something as elementary as running your application it naturally applies to many aspects of the developer s day to day debugging testing even just writing new code to see if it works Therefore solutions that make your application even a little easier to run provide significant value just by affecting so many routine activities In this article we re going to discuss today s dominant approaches to making microservice applications easier for developers to run and we re also going to make the case for our own thing namely a single shared environment in the cloud that the organization maintains and that developers can plug in and out of non intrusively as they develop their microservices Contemporary Cloud Development WorkflowsIn the frictionless microservice utopia the development workflow goes something along these lines Microservices are independent and new functionality can be developed one microservice at a time Microservices talk to each other via well defined contracts which can be tested in isolationDatabases queues and third party services consumed by a microservice also expose a consistent and well defined contract and as such can be mocked for testing purposesIn other words a service can be tested on its own and then deployed to the production environment where it would play nicely with all the other components However let s assume you re a microservice developer who doesn t work in an organization where everyone designs perfect contracts and writes rigorous tests or they do but the third party managed services you rely on don t When writing new code you probably make as much progress as you can within the scope of the one or two microservices you re working on at the moment but then you do one or more of the following Wrangle your entire application microservices databases and all to run on your local machineDeploy your new code to a personal persistent ephemeral development environment in the cloud Deploy your new code to a shared staging environment and test it there Run LocallyThis approach works great when it s feasible which is usually at a very early stage in the life of the application where it s still small and tenable There s some tooling that lets you extend this honeymoon phase by letting you do it more easily like docker compose Skaffold or Tilt However at a certain point even if you ve written whatever scriptage is needed to actually configure and run the latest stable version of all of your components together you re going to hit some sort of ceiling if you ve got a large database or some CPU heavy computations or you re relying on some managed service that can t be containerized this approach soon becomes untenable Pros Convenient development on your local machineNo reliance on network or external servicesCons Difficult impossible for large applications ones with e g many microservices a large database high bandwidth usage Doesn t support hard to containerize components like managed services Personal Cloud EnvironmentWith Infrastructure as Code at its current state of maturity it s now easier than ever to replicate microservice environments in the cloud This unlocked a new approach of having a personal production like cloud environment for every developer which they can use freely and in isolation It comes in two flavors persistent environments or ephemeral environments created on demand with products like Okteto or Bunnyshell also sometimes called Environment as a Service This approach overcomes the resource limitations of the local environment but substitutes them for some new difficulties For persistent environments cost determined by the size of the environment times the number of developers becomes a factor As the company grows so do its architecture and the number of developers leading to soaring cloud billsTo generate state database seed files are used These need to be maintained so they don t become staleYou have to work against a cloud environment which isn t always fun though some tools make it easier like GitHub Codespaces or Gitpod Same as with running your application locally having hard to containerize components in your architecture like managed services can make this approach unfeasible Pros Not capped by the hardware limitations of your development machineBetter simulation of your production environmentCons No production like database stateLocal changes have to be synced to the cloudDoesn t support hard to containerize components like managed services Shared Cloud EnvironmentA lot of organizations have already put in the effort of setting up a single shared production like environment for testing the staging environment It s persistent and has already been set up manually to include all components including third party services databases with full state some companies even automatically stream data from production and all the microservices In terms of simulating production it s hard to do much better However since this environment is shared by multiple developers some measures are usually in place to keep it stable for example you can only actually deploy new code through the CI often meaning you have to wait for a code review and your entire suite of automated tests to run not to mention the deployment script itself before it actually gets there Even then the tests aren t perfect and sometimes you end up deploying broken code and corrupting the environment much to the chagrin of your fellow developers This is where shared environment tools like Telepresence and CodeZero can help They assume you re only working on one or two microservices anyway and running them locally is not an issue These tools let you connect your local service to the staging environment replacing the service currently running in the cluster without deployment The code you re working on runs locally and its dependencies run in the cloud Not only can you keep working on your local environment you can iterate on testing against your cloud environment without waiting for lengthy CI and deployment processes Pros Leverage a single shared environment making it feasible for you to manually set up database state and managed services since you only have to do it once for one environment You can still work locally within your IDECode changes happen locally so iterations are fast no need to deploy to the cloud Cons One developer can break the environment for the othersIf the environment is corrupted it s hard to recover The SellSo local setups are easy to use but don t support large deployments personal cloud environments support large deployments but don t really reflect production don t support components that can t be containerized and cost a lot and shared environments reflect production for cheap but don t really support concurrency without sacrificing stability mirrord lets you have all of these cakes and eat them too We essentially took the shared environment approach and tacked on isolation We do this by Letting developers mirror incoming traffic rather than just intercept it This lets multiple developers work on the same service in the cloud while the service is still running and handling requests Giving developers fine grained control over what happens locally and what happens remotely This way for example incoming traffic mirroring and file reads can happen remotely but outgoing traffic and file writes can be local Future versions of mirrord will include more advanced modes of configuration letting users filter by e g hostname or protocol In future versions supporting advanced features like copy on write for databases In our upcoming cloud solution providing RBAC letting the organization control which teams have access to which parts of the staging environment By using mirrord developers can run the one service they re working on locally without juggling configurations or straining their development machine they can run it against a full environment with mature database state and managed services and they can do it quickly easily and without risk We ve recently released our first stable version and would love to hear your thoughts on GitHub or Discord It can also be supplemented with a cloud development environment as provided by products like Gitpod or Codespaces For a comprehensive survey of the non localhost space see this excellent article	2022-11-15 15:47:30
海外TECH	DEV Community	How Singula team helped develop an analytical system for a tire manufacturer	https://dev.to/elizabethlvova/how-singula-team-helped-develop-an-analytical-system-for-a-tire-manufacturer-40on	How Singula team helped develop an analytical system for a tire manufacturerPirelli amp C is one of the world s largest manufacturers of premium car tires The company owns factories in countries all over the world In the Tire Plant owned by Pirelli amp C decided to develop a manufacturing analytics and IIoT system for analyzing the enterprise s production processes But ready made solutions out of the box could not offer the necessary functionality So the company turned to Singula with a request to help them develop a unique data analytics system for manufacturing production which would allow the data to be analyzed and visualized and let them see bottlenecks The challenge collect data from hundreds of machines in one placeThe plant has hundreds of machines that perform millions of operations every day At the time all the raw data on them were sent to one large common system Each department unloaded and processed it manually which took a very long time While they could unload data from the system via SQL this had to be done by specially hired specialists Then each department prepared a report according to its profile planning quality assessment etc As a result top management collected several different reports and based on the data received a certain general picture of production But thousands of such reports were collected for a shift a day a month etc To create the annual report employees in each department had to manually process huge amounts of data This took up most of their work time The plant needed to develop an industrial analytics platform that would increase the efficiency of operational processes take over the primary analysis and processing of data and issue it in an easy to understand form using graphs tables and diagrams Basic system requirements Ability to work with different data sourcesIntegration with enterprise information systemsReporting platformFlexible output of results in the form of graphs and tablesAuthentication and authorization of system usersDeployment within the international corporate standards of PirelliThe solution analytics and cluster structureBusiness analyticsWe had to come up with a unique industrial data management platform so we did a lot of preparatory work before beginning the manufacturing monitoring system development In the first months two Singula team business analysts worked on the project studying architecture and use cases of existing databases and user requests for a future product The technical team also visited the enterprise and got acquainted with the technological cycle and equipment in order to understand how production works and the existing internal bases and systems Currently one analyst is working on the project He is engaged in clarifying the needs of the client collecting feedback on ready made solutions and formulating tasks for developers All communication with the client s technical team most of which is located in Italy goes through him Big data in industryWe needed to develop an application for the collection and primary processing of big data in manufacturing The company has an industrial Internet of Things IIoT system In addition to data on the direct operations of the equipment operating times and types the number and duration of cycles and failures the machines also send data about various rubber compound formulations and tire models to the databases This information flows into local databases and then accumulates in the general Data Lake Pirelli Management and access to data occur through the internal system of the corporation We taught the application to quickly find the necessary data in the storage filter it according to the specified criteria and then build tables graphs and charts based on it But the application does not just collect archived data it is also a real time production monitoring system allowing users to monitor current processes and report failures and violations In addition users can correct the results in which case the edited version is saved separately Technology stackThe main platform for launching and managing running applications is Kubernetes We chose this platform for several reasons One of the main ones is the ability to flexibly and quickly scale environment resources when the load on services increases especially when the number of analytical modules in the system increases Built in isolation mechanisms allowed us to work with data safely and accurately Colleagues from Italy have already transferred some of their services to this platform and we quickly optimized our deployment processes to work in the global Kubernetes environment thanks to unified approaches and tools supported by the global DevOps community The distribution of the application is implemented through Docker which allows us to quickly deliver changes to the production environment using the optimal development languages ​​for specific tasks as well as to flexibly switch between releases The entire process of building and delivering releases is automated using CI CD tools and services which eliminates the influence of the human factor in these processes The application is written in Python using Django and React is used on the frontend To work with databases a layer in the form of a Query Engine is used which allows you to flexibly manage access to tables as well as optimize and parallelize queries when working with big data Caching of frequently accessed data is implemented using Amazon ElastiCache DesignThe request for the interface design of the BI tool came from our development team not from the client as is usually the case The client was not satisfied with the initial prototype using ready made solutions ーthere are too many different forms of data in the project and it was extremely difficult to find the information of interest in the final graphs using existing BI tools in the manufacturing industry It was necessary to take into account some conventions that are already accepted in the company For example color coding Conditional colors are used to indicate different groups of data There are also preferences for chart types ーmost often Pareto and waterfall charts are used We have written scripts for different user groups to make the system more convenient for different specialists to work with You can choose the period for displaying statistics the number of machines production cycles and so on The most useful buttons have quick access so that interface elements do not interfere with the perception of basic information Result MVP release by modulesThe implementation of this analytics system is divided into modules responsible for different aspects of production which we are implementing in priority order for the customer There are parts in the project and three of them have already been released into production New sizesThe first module is responsible for monitoring the Phase In processes ーthe transition of equipment to new tire size and the production of that size In this case there are two types of Phase In ーBU and CU for which the sets of control points are different To analyze these processes and optimize the performance of production we taught the application to collect control points for all stages of production assembly vulcanization and finalization and compare them with normal indicators so that any deviations are immediately noticeable Equipment efficiencyNext we implemented an OEE system that allows us to evaluate the performance of the equipment It operates with data on the operation of machines directly without reference to models and recipes Data can be filtered by dates shifts types of machines specific machines or you can reset all filters and see a general summary table Working cyclesThe third module allows you to track equipment cycles and the performance of operators The system generates statistics on the time of work cycles for machines rubber models and operators ConclusionIf you are also looking for custom manufacturing analytics solutions or production intelligence apps for big data and industrial processes send us a message our experts will help you to develop a custom product based on your requirements	2022-11-15 15:38:54
