The benefits and potential of microservices are recognized by both users and non-users in the current period and the real-time users’ confidence in the future of microservices is great. This may sound astonishing but reports say that 78% of current users say their business will likely increase the amount of money and effort invested in microservices and 56% of business bodies say that they are likely to adopt microservices in a couple of years.
“If you are working in an organization that places lots of restrictions on how developers can do their work, then microservices may not be for you.” quoted by Sam Newman
What Are Microservices?
When Should You Use Microservices?
To adopt agility, manageability, scalability, and delivery and performance speed in the monolithic application
To update your legacy applications in present-day’s programming languages or tech stacks to match with business trends, requirements, and solutions
To predict the types of devices on which the app is going to run when the developers are unable to decide
To support the incorporation with the help of a skilled data management team
To use standalone modules across diverse channels
To be compatible with a highly agile application development demanding accelerated speed of delivery and creativity
Benefits Of Microservices
Microservices fit right with both Cloud and DevOps. As almost every company started moving their workload to the cloud and microservices play the role to complement cloud-based application architectures by allowing an app development team to use patterns for say event-driven programming as well as autoscale scenarios.
Its main benefits are:
Agility and Affordability Scalability
Higher- Quality End Product
Real-Time Processing
Data Isolation
Enjoy Limitless Integration
Steps To Introduce Microservices
STEP 1: Identify whether Microservices are a good fit for your business or not
Initially, you have to determine whether microservices match your business’s perspective and goals. Only after knowing the requirements, capabilities, and outcomes, you should move forward with implementation as the application process will be complex. So, it is mandatory to have the access to adequate software engineering skills and microservices expertise in your team.
If that is not the case, an already created simple application with a monolithic approach will be more suited for your team’s needs. If after determining you think that Microservices is the right ap
STEP 1: Identify whether Microservices are a good fit for your business or not
Initially, you have to determine whether microservices match your business’s perspective and goals. Only after knowing the requirements, capabilities, and outcomes, you should move forward with implementation as the application process will be complex. So, it is mandatory to have the access to adequate software engineering skills and microservices expertise in your team.
If that is not the case, an already created simple application with a monolithic approach will be more suited for your team’s needs. If after determining you think that Microservices is the right approach for your business then you should make a long-term investment for its training and development.
STEP 2: Define your goal and path to achieving Microservices
If the business perspectives and microservices architecture is a good match then it comes to the point where microservices goals need to be defined. A goal map or path should be outlined and the flow of moving towards it should be defined. If you don’t have a plan ready for how this is going to work then because of Microservices’ individual nature to add multiple services may cause complexity and chaos. This step may vary from company to company as every business has different goals and different ways to reach them.
Even though you are building everything from scratch or transitioning from monolithic architecture, this step is important to define the goals and set the boundaries between the services.
STEP 3: To implement microservices, adopt a headless CMS platform
This headless architecture enables the development and deployment of the back-end independently of the front-end architecture. It simplifies the process of implementing microservices as you will be able to develop each service independently as well as makes it even more efficient.
This will give access to your team to build, optimize, deploy and manage the content modules without interfering with the design and development that goes around on different channels and devices.
Adapting to CMS will let you use the modern technologies independently without holding you back.
STEP 4: Construct planning for deployment and Agile systems
A publish-subscribe framework enables the data processing in real-time. Eventually, extensible systems can go through and process a large number of data in real-time.
STEP 5: Plan documentation and prepare a maintenance schedule
Numerous microservices performing concurrently in various departments might create a state of fuss for the based marketing platform.
Planning for ongoing documentation and maintenance as monitoring and recording errors can keep all the parts moving smoothly together. This culture can promote the concept of keeping high-quality technical documentation and algorithms which go conjointly with the coding.
STEP 6: Initiate a small project
After following the process make sure that everything is in its place and release a small microservice project at first before implementing it completely.
It doesn’t matter if you are transitioning your entire business with microservice architecture or just adding a few services, swiftly rolling out just one of it initially can give a better understanding of its requirements and run the decoupled architecture efficiently.
With this, you will be able to figure out where you are lacking or failing and learn how to hold out in a controlled environment.
Microservices VS Monolithic
Explaining monolithic architecture – An application developed with monolithic works as a single unit, where all features, functionality, and segments are closely-bounded for integration, deployment, and development.
When comparing Microservices with SOA there are a few points we should focus on:
Design
In microservices, independent services communicate via APIs. Monolithic is designed as a complex app encompassing several tightly-coupled functions.
Scalability
Agility
Service startup
Data consistency
Team communication
Monolithic does have comparatively straightforward team communication than microservices.
Finding failure points
Microservices VS SOA
Service-oriented architecture (SOA)– Created as a response to the traditional approach for decoupling an application into smaller segments. And to meet specific business requirements these individual service segments intercommunicate. It is often considered by many developers that microservices are a subtype of SOA, while few insist that each works on a different set of problems.
When comparing Microservices with SOA there are a few points we should focus on:
Design
Scalability
Data Storage
Component sharing
SOA does involve component sharing but microservices do not involve component sharing generally.
Deployment
Remote services
Examples Of Microservices
Microservices in general can be proven valuable for the development and growth in various sectors like healthcare, online marketplace, eCommerce, social media networks, finance, and many more. To understand the concept of how it can be utilized practically we can see the below-mentioned usages:
- Including new desired functionality to a large legacy system
- Accumulation, composition, and analysis of a data flow for machine learning environments
- To handle big data, it provides scalability and control
- It’s one of the uses is to enable advanced analytics environments to validate their updated computational models with the help of AB and multivariate testing
Only because of the microservices architecture examples discussed below it was possible to make the world understand how the transition from monolith to it could make a change!
Netflix
As a matter of fact, Netflix is surely considered a role model by present-day cloud-based companies for using microservice architecture. Netflix, known for streaming various content of different languages online started building up its microservice architecture on AWS in 2009. Within just two years, Netflix relocated to microservices from a monolith partitioning it in stages. In the initial stage, they adapted changes in movie encoding and other applications which are not used by customers. Then they shifted to decouple customer-facing segments like movie selection, account sign-ups, device selection, and configuration.
Amazon
Amazon serves as the world’s largest online retail platform. For years Amazon was in the habit to run on an extensive monolithic application with many flexible yet closely-bounded components. In consequence, Amazon could not further bifurcate its teams into smaller parts to fast up the speed of its development cycle. Then, the company diverged the code as independent functional services, enfolded with web services, and ultimately advanced to these services.
Best Buy
Best Buy commenced revamping its eCommerce platform in 2010 with the mission to break the monolithic, closely-bounded application into microservices for the swift rollout of new features and react to market changes in the retail marketplace.
Conclusion
Microservices architecture is the nearest perfect solution to the digitally developing world which needs to deliver faster functionality and reliability. However, the transition from monolithic to it can be lengthy and tedious. Its suitability depends on the project scale and requirements. Usually, they are preferable to modernize legacy systems and also for cost reductions, enhanced collaboration, integrations, and data consistencies.
