Introduction
In today’s fast-changing world, technology is upgrading at a more rapid pace, which no one ever imagined. The need for newer and faster technology is increasing with each passing day. Here we are going to talk about some of the modern technologies which are gaining popularity these days. The combined benefits of both changes the entire science of Software Development Automation. In this blog, we explore the benefits and strategy for DevSecOps with Microservices.What is DevOps?
DevOps is mainly a set of practices and tools that help in continuous delivery and shortening the software development life cycle by automating the processes between development teams and software development. Along with increased development speed and distribution, reliability is also maintained. The idea of DevOps, the idea was born due to security issues in DevOps, which was referred to as DevSecOps.DevOps helps to Automate, Monitor, and Analyse Application Delivery with Continuous Container Delivery Pipeline.

What is DevSecOps?
DevSecOps is the practice/philosophy of adding security to DevOps. According to the approach, everyone should be held accountable for safety, and security should be implemented alongside the development without affecting the outcome of the programs. So where is the difference between these two? Both DevOps and DevSecOps follow the Continuous Integration/Continuous Deployment strategy. Despite being similar in most aspects, these two still have differences.
How to Build an Effective DevSecOps Strategy?
An effective DevSecOps strategy can assist you in a variety of ways, including increasing product sales, improving overall security, and delivering software more quickly. However, a single misstep in strategy development could be fatal for your business.
Here are a few tips to draft a DevSecOps strategy effectively.
Guide your team
One of the most critical obstacles that most businesses face when adopting a DevSecOps strategy is hesitancy. DevSecOps necessitates a fundamental cultural transformation. People are unlikely to adapt to new changes. To avoid this, we recommend training development, security, and operations teams on the DevSecOps cultural shift and benefits.
Conduct security audits
Security audits are required to understand the existing state of the system, identify security vulnerabilities, and investigate opportunities. Analyze the present system using both internal and external resources.
Automate tasks
Automating business operations can improve project delivery and customer satisfaction. Furthermore, it ensures that the DevSecOps strategy is implemented smoothly.

Difference between DevOps and DevSecOps
The main difference between DevOps and DevSecOps is information security. DevSecOps is known to be DevOps with added security features. Due to the lack of required security measures, the management of risks/problems during the phases was not done. With the security features in DevSecOps, the concept of continuous risk management was also introduced to the development/production.What are Microservices?
Microservices or popularly known as Microservice Architecture is a Software Development Architecture technique or style that decomposes or divides the application into a set of loosely coupled services. These services are:- Independently deployable
- Highly maintainable
- Owned by small teams
- Loosely coupled
Microservice architecture is a successor to monolithic development architecture, in which, instead of the decomposition of application into services, the app is developed and deployed as a unit file. One of the benefits of this architecture is that it helps in faster and continuous deployment, also, if there is a problem with any service, the service can be rolled back and checked for errors. With the help of the Microservices strategy, we can roll back no value-adding services at any time.
What is the use of microservices in DevOps?
Microservices is an architectural term that refers to the process of creating a distributed application using independently deployable services that perform specific business operations and communicate over web interfaces.
Containers for Microservices
Microservices architecture-based applications should be deployed and executed using containers. Boxes are packages for our application/software that contain all the needs of software like libraries, code dependencies, binaries, and some other necessary tools. The container has become popular because of its several benefits over its opponents, such as Virtual Machines(VMs), etc. Some of the benefits are:
- Containers provide continuous development, continuous integration, and deployment, which makes deployment and rolling back easier.
- Containers provide Environmental consistency in development, production, and testing as they run the same way in every environment, whether it is a personal laptop or the cloud.
- Boxes are beneficial in handling Microservices.
Some tools can help with Microservices and containers. Here are some:
Kubernetes
It can be defined as a platform to manage containers and services/ workloads which are containerized through them. This is a high-speed growing tool, which was first published as an open-source Kubernetes project in the year 2014. It is a solution to the container handling problem. If a container has some issues or questions, then the work will terminate. Kubernetes handles these issues by starting another box if the previous one fails.

Docker
Docker is a containerization tool that helps encapsulate applications in containers and manage those containers. In Docker, there are no conflicts, and microservices of applications run separately in their container environments. In Docker, we can create a stable environment for application execution by using the necessary libraries, languages, and dependencies. Some of the advantages of Docker are:
- Docker images can be created and saved in case we need to run them on different servers.
- For Docker, a container is an operating system process, so the starting/loading time for the boxes is very less(merely a few seconds)
- Management of containers is secure, and they can be created and destroyed in a few easy steps.
- It supports various operating systems, including Windows, many Linux distributions, and Mac.
DevSecOps and Microservices
DevSecOps and Microservices both are very helpful in software development automation. By combining these two, both software quality and deployment speed are increased. Also, it handles security issues during the development, production, and deployment phases. When we combine these two technologies, it becomes easier to develop independent microservices for a software/application parallelly. The DevSecOps microservice architecture ensures Continuous Integration/ Continuous Delivery with increased security measures. As microservices are independent and loosely coupled, development becomes a little easier for developers using the strategy. Also, Microservice architecture acts as a boost for the speed of DevSecOps-enabled applications development. Some of the Benefits of using DevSecOps with Microservices are:- Errors are reduced
- Product quality is improved
- The development effort and hence the cost is reduced
- The productivity of Development teams is increased
What's Next?
We have made several points above showing the benefits of combining DevSecOps with Microservices. These two are part of the leading technologies in the world and are still growing at a fast pace. The combination
of these two will increase the software development speed, security, and reliability and will be a great help to the developers who prefer to use the DevSecOps strategy. The organizations which are applying this combination strategy are becoming more productive and are leaving their competitors behind with faster production and lower cost.
