Here are three (4) fundamental reasons why you should implement a Microservice architecture.
If your business system is composed of several large-scale moving parts and large teams. In the case a function or domain can be maintained independently by a designated team this enables team independence.
If your business is built on outdated systems.
When the application requires multiple resources and expects high traffic.
If your business relies on homogeneous systems that use the same technology for every aspect of deployment.
Testing different processes with microservices allow you to choose the right technology for specific service deployments. Popular companies like Netflix, Amazon, Walmart, and Spotify have all successfully used microservices architecture; here’s how it went:
Netflix
In 2012, Netflix restructured from a monolithic service to microservices, and by 2017 the architecture had over 700 loosely coupled microservices. They were able to address certain issues with service outages and scaling. This move reduced their cloud cost significantly.
Amazon
Amazon adapted microservices to address issues regarding scalability. The e-commerce site was built on a single application, which was complex, difficult to maintain, and scale; the company now manages its e-commerce company with hundreds of microservices.
Security Challenges and Solutions for Microservices Architecture
There are many services in a single application and this comes with its set of challenges, here are some security challenges microservices face;
Increased attack surface
Different services are run on different ports, exposing these ports and APIs, and causing a security vulnerability. In this case, microservices must be secured tightly to prevent malicious attacks.
Isolation Failure
This can occur when one microservice fails to communicate with another microservice. This causes security concerns in microservice architecture because it can result in access to sensitive data or the failure of vital functions. Implementing robust security measures such as communication protocols, encryption, and firewalls reduces the risk of isolation failure. Regular testing and monitoring of applications also prevent system failure.
DevOps
When an application is being released or tested, security vulnerabilities are likely to occur. DevOps must be able to identify, evaluate, and manage risk. Also, DevOps must work closely together to ensure the success of a microservice architecture.
Fault tolerance
The capacity of an application to continue operating when it develops a bug or if one or more of its components stop working is what we call fault tolerance. The likelihood of failure increases when a large number of services are interacting over a network. This means that in order to prevent interruptions to your entire application, the server must be able to handle service failure. Failures in microservices can be handled by fallback measures like a circuit breaker.
Best Practices to Build Secure, Scalable Microservices
Data and API Security
Due to the communication between services, there must be tight security to prevent exploitation. Security certificates must be maintained, and data must be encrypted. Access to APIs must be scrutinised, therefore, only authorised users must have access to them.
In-Depth Defence
Defence-in-depth is a way of protecting microservices. By incorporating several layers of security control into an application, you can protect critical services. If an attacker gains access to one component of an application, additional security measures may prevent the attacker from attempting to exploit other components.
API Gateway
API gateway is in charge of directing traffic or routing incoming requests to the relevant Microservices. The API gateway is secured using token-based authentication. It is advisable to add a layer of protection around the attack surface by placing it behind a firewall to prevent exploitation.
There are several tools for building a microservice application.
Tools for API management and testing e.g API fortress and Postman, etc.
Messaging e.g Apache Kafta
Monitoring e.g Logstash, Graylog, etc.
Programming languages e.g spring boot, elixir, etc.
Toolkits e.g fabric 8, serverless tools e.g serverless, Claudia, etc. just to mention a few.
Conclusion
Distributed systems are complex, and they have their pros and cons. From the standpoint of microservices, we can separate the various parts of an application into smaller, independent teams that concentrate on smaller codebases. This method makes it simpler to manage the application, address bugs, and effectively add new features.
After understanding what microservices are, we'll discuss how to create them using a variety of tools, some of which are mentioned above, in later articles.
