Architecting fast is the key until its not In my years career as a developer consultant and recently as Cloud Architect I have worked with companies of all scales I have had a taste of multi national corporates mid size product companies and startups alike All these places have had different set of challenges but there was always a common theme I could see everywhere Most of these challenges were rarely related to technical complexity These mostly had developers struggling to understand what they were supposed to produce The architects product managers tried hard to be precise but despite of all the efforts the result wasn t any different Looking at those scenario s in retrospect with a trained brain a brain that has gotten a little better at finding patterns over time I found root cause for most of the misery pointed to one direction Someone somewhere in the organisation decided to put technology before business This phenomenon occurs when it is decided that the business vision can be achieved by throwing software at it If you hear Hey this can be solved with Ks insert any other tech early into the process of defining project it has already been set on a slow path to graveyard As a relatively young architect the more I reflect on these scenarios the more I am convinced a dire need in shift of our focus from it can be solved by tech x to spending time to understand the intricacies of the core business Inspired by Domain Driven Design approach the problem should be tackled in steps Each step provides a separate set of outcome that helps to realise good software Step Ask questions starting with WHY to domain expertsThese would generally look like Why are you looking to build this Why now Why not earlier or later Why use technology to solve it Why cannot it be addressed via processes or new methods Why does the business or its end users need this These questions will vary a lot from domain to domain project to project At the end of the exercise however you should get a set of reasons that will help you define the Non Functional Requirements for the software system Step Ask questions starting with WHAT to domain experts or end usersThese would generally look like What do you expect the software to look like What are the functions you expect your software to perform What kind of operations do you plan to support via this software and many moreThese questions should set you in the right direction of setting up your high level requirements This exercise should be strengthened by performing the exercise of Event Storming More about event stormingFollowing the why questions and event storming you would have wonderfully descriptive business process that need to be modelled into the softwaregreat idea on how to draw boundaries in softwarehow the stakeholders envision the end state of the softwareThis would turn into actionable user stories which in turn lead to well defined tasks Everyone is happy Step Ask questions stating with How to technology stakeholdersThis is where you should set your inner techie free Since you now have the elaborate requirements you can focus on using the right technology for the right job Now is the time to deliberate technology choices with yourself or tech peers You have NFR s as well and tech needs You have been set with right details to make accurate choices for the software This isn t a gospel and things might work for you differently The core message is we need to slow down a little and make technology work for business not the other way around Happy Architecting |

Microservices Architecture: What, Where & Why? |
https://dev.to/anubhavitis/microservices-architecture-what-where-why-106g
|
Microservices Architecture What Where amp Why If you are into software development you ve probably heard about microservices They ve acquired a lot of traction in recent years and every major corporation is creating one Microservices are an innovative and very unique approach to developing application systems as a collection of small services each performing discrete and well defined functions and being deployed independently They are easier to understand easier to deploy and can be shared across different systems This method brings high agility to an application system and provides many opportunities for DevOps and CI CD In this article you are going to learn about Microservices architecture of application systemsVarious benefits of building microservicesMicroservices development tools and technologyCommon patterns for implementing microservice architectures Different architectures of application systemsIn terms of architecture there are two sorts of application systems the first is centralized and known as a monolith whereas the second has a decentralized architecture known as microservices MonolithsAn application is composed of three components a server a client and a database The server processes client requests implements business logic collects or stores data in the database and responds to the client These kinds of servers are referred to as monoliths A monolith is a straightforward approach to building a server application They re made up of classes and functions that let you combine all of your business logic into one running process This is a single executable application system where every change results in a newer version of the system Kinda like Thanos with all infinity stones Monolithic systems are ideal for launching a business since they are self sufficient offer fast communications and their requirements are easy to define However when a business grows monolithic systems become a challenge They have low scalability and adaptability and require extensive maintenance even small errors at any point cause the entire system to crash in a split second Also they do not allow various teams to work independently and are constrained to be developed on a single technology MicroservicesThe microservice architecture is the solution to the challenges faced by monolithic systems Rather than creating a single full fledged server program with a dedicated data storage unit this system consists of multiple microprograms serving unique services thus referred to as a microservice Kinda like a team of superheros with specific roles and abilities Microservices are built on specialized business capabilities They have their own running process and can even have their own data storage unit Different microservices can employ different programming languages different database approaches and be deployed independently Different teams in the company work on specific services and updates result in newer versions of the affected microservices rather than the entire system And at any point of error only the affected service will fail the rest of the programs will work just fine Why microservice architecture More than of enterprises had switched to microservices architectures by Many large corporations such as Amazon Netflix Twitter and Paypal which began as monolithic systems were at the forefront of this transformation Its modular approach in application systems is widely being adopted to handle complex applications Let us take a quick look at some of the real world use cases of microservices Refactoring Legacy ApplicationsIn this competitive world businesses often need to refactor their legacy codes or move to new technologies Microservices is the preferred architecture by enterprises for rebuilding their system to change the functionality add new features or move to a new technology stack Big data AI MLApplications that use technologies such as big data artificial intelligence machine learning and so on need complex data pipelines for operations such as data collection data filtering data processing and so on In this scenario a monolithic design could make the system heavy and difficult to administer instead a distributed system architecture with segregated pipelines is the better option Real time data processingMicroservices architecture is used by streaming platforms such as Netflix and publish subscribe pattern apps such as Twitter to provide smooth asynchronous communication and real time data analysis to produce intelligent outputs Netflix was an early adopter of microservices and now has more than microservices working autonomously to provide you with the best performance available DevOpsWhen DevOps and microservices are used together they work incredibly By adopting a single toolset that can be used for both development and operations microservices help the DevOps team be more efficient Project requirements task dependencies and problems may all be described using the same terminology and techniques Microservices like anything else have their own pros and cons You must be aware of both of them before integrating this architecture into your system Benefits of using Microservices Technical benefits for developersYou have the freedom to use different programming languages tools technologies and data storing strategies based on the requirements of your service Since every microservice is isolated results in fast defect isolation too failure in one microservices won t affect the rest of the system You can easily integrate or transition to new technology for a specific microservice without affecting the whole system Microservices are simpler to understand for new developers as compared to understanding the whole system Benefits for organizationsMicroservices save a huge amount of time and money by making the system easy to manage and optimize Different teams in an organization have the freedom to work independently without colliding with other teams Microservices are based on distinct business capabilities so they can be easily developed by a small team Since a service can be shared among different products this saves a lot of resources for an organization Drawbacks of using MicroservicesTesting can be a very tedious task in microservices architecture since there are a lot of services to test Handling the entire product might get difficult as the number of services increases Developer needs to design and develop a lightweight robust and secure communication system for microservices to communicate with each other Internal communication between microservices increases the time taken by servers to respond to clients Microservices development tools and technologyAs microservices architecture gained popularity more and more tools and technologies have emerged to support this practice and improve the developer experience Here are some of the best technologies for developing microservices ContainerizationOne of the most key traits of a microservice is that it operates independently as autonomously as possible To maintain their autonomy they must be kept in an isolated environment with their own runtime environment Containerization services such as Docker AWS BottleRocket and others make this feasible Through autonomous container based microservice architecture you have the freedom to add remove scale and replicate components as required by your business API ManagementWith an increasing group of microservices comes the challenge of establishing safe connections between them You certainly cannot risk exposing any of your microservices to public networks API management using services like AWS API Gateway Azure API Management reduces the time required to build and manage API connections between microservices They have various capabilities like authentication services API monitoring and so on which may save developers months of time and work Continuous Integration Continuous Deployment CI CD If you re adopting microservices architecture you don t want a lengthy and costly release train where each team needs to wait their turn You also don t want the release of one service to impact or be impacted by the release of another You need to employ continuous integration and continuous deployment pipelines for your microservices You can use CI CD platforms such as Jenkins and AWS CodePipeline that provide easy to set up automated but high velocity releases for your microservices Application Performance Monitoring APM toolsYour microservice is up and running after you design implement test and deploy it but you re not done yet You must monitor system performance in order to improve user retention and rid your systems of faults and bottlenecks Application performance monitoring solutions such as AWS Cloudwatch Kibana allow you to effortlessly monitor all of your microservices as well as increase your mean time to repair mttr by detecting problems sooner Cloud providersManaging multiple microservice can be very challenging you need a lot of containers API management tools host multiple databases CI CDs Application performance monitoring tools etc But no worry most cloud service providers like AWS Azure IBM etc provide all of this on their platform which eventually makes managing microservices lot simpler Common patterns used to build microservicesThere are plenty of design patterns available for building microservices each of them with different priorities and solving different problems Here are some of the most popular patterns for building microservices Database architectureDifferent services may require different data storage techniques therefore creating a separate database for each service is a realistic solution that will improve scalability However running searches that connect data from several servers becomes quite complex Creating boundaries that ensure modularity is a smart notion As a result we may keep the data of a microservice private to that service but we must make it available to other services via APIs API gatewaysMaking microservices accessible to client applications is a challenging task in itself You don t want to expose all of the services to all sorts of customers and some services even implement API protocols that aren t web friendly There are many service instances and their location host port varies dynamically A single access point for all clients such as an API gateway is a viable option in this case This API gateway checks client requests before routing them to the appropriate microservice It can send requests to a single server or several servers depending on the requirements credits Foundersguide Access tokensConsider the following scenario you ve implemented microservice architecture and implemented an API gateway as the entry point for all client requests Requests are directed from here to various services based on their requirements but how do you convey the requester s authenticity to the service that executes the request As a result the API gateway passes an access token e g JSON Web Token along with the request which securely identifies the requestor in each request to the services The access token can be included in requests to other services by a service Log aggregationRequests commonly span various service instances in a microservices architecture Each service instance saves logs in a defined format to a file Errors warnings information and debug messages are all stored inside this log file Debugging an error on the other hand might be time consuming if you have to go through all of the services log files As a result having a centralized logging server that collects logs from each service instance is preferable Different logs may be searched analyzed and even alarms can be created by users Health check APIsEven if a service instance is unable to handle requests it may continue to run It might for example it has run out of database connections The monitoring system should raise an alert system if this happens and requests should not be sent to the failed service instance So it is very crucial to identify whether a running service instance can handle a request of not As a result a service s health check API endpoint like health that returns the state of the service should be included This API endpoint handler checks a variety of things including the status of the service instance s connections to infrastructure services the state of the host and application specific logic You can learn more patterns for building microservices from here Phew Looking back you began with learning about various application system designs followed by many famous microservices architecture use cases and then the benefits and drawbacks of adopting a microservices architecture Furthermore you learned about numerous microservices tools and technologies for building microservices as well as some typical patterns for making them efficient Hope you found the article useful Thanks for reading Happy coding |
