In today’s software development, the core development gurus and the operations teams work together. Unlike past, when both these teams did not work collaboratively, today they both combine to become what we call DevOps. This means that a single team is now responsible for both software development and further deployment, testing, deployment, and infrastructure management. DevOps also ensures that the work is done through continuous integration and a continuous delivery model.
DevOps with Cloud Computing
So how do we bring the teams together?
Through the birth of Cloud, it has become possible to bring all the resources and the teammates one a single point. This point is the remote Cloud. Thus, DevOps and Cloud computing have become inseparable teams members. This gives birth to a whole new concept called Cloud native DevOps.
There can be many ways in which an app is deployed. Apps that are designed to live on the cloud from the scratch are called Cloud-Native Apps. These apps rely on the infrastructure provided and maintained by Cloud services providers such as Amazon. All the resources needed by the app to run are offered by the Cloud. Such an app is not limited to Cloud offerings but is preferred to connect to the Cloud.
The reason for the apps to go on Cloud is because Cloud offers scalability and reliability that is unmatched for the on-premises deployments. The burden of managing the infrastructure and resource provision is also removed from the development or DevOps team.
Apps running on the Cloud depend upon some principles.
Microservices meaning that a large system is broken down into smaller systems so that a small team can work on only their part. Software teams work collaboratively through loosely coupled services. Microservices solve the problem of vertical scaling and the tightly coupled nature of the applications.
So, if you have multiple microservices how do we deploy them? How can we stop them from interfering with each other? Containers provide the answer. Containers are a new way of hosting applications with each application residing in its isolated environment. It is preferred over virtualization as it allows horizontal scaling of the application.
Serverless is the new way of hosting applications. Traditionally, applications needed to be hosted on some compute service. In Serverless computing, the developers do not need any computing service. The infrastructure is fully provided by the Cloud provider. All a developer needs to do is to code the application and it's ready.
DevOps Act in Cloud
DevOps is a foundation stone today in software development. Even the best-written code needs updates, upgrades, and maintenance. The issue comes when the team is big and the updates to the code base are very regular. In such scenarios keeping track of changes, tasks and statuses become a tedious task. What if fixing a security vulnerability starts to crash the fundamental features.
A good DevOps culture can help boost the software team’s productivity. What took a month to deliver can be delivered within a week or two by implying the best practices of DevOps. DevOps provide a good 360-degree view of what is happening in the software development process. Having this DevOps on a Cloud ensures that the whole process is streamlined, accessible to everyone, get live updates, view pipelines, view build statuses, view previous builds, manage infrastructure, plugin more and more services, additional tools, and plugins, without having to worry infrastructure maintenance.
One Step Forward: DevSecOps
This is where the Cloud Native DevOps gets interesting. Software systems do not run standalone. They have to connect to the internet with other services. This might be to fetch data or provide an online experience. But with the online presence also brings with it numerous security threats. The issue of cyber security is growing day by day. More and more cyber-attacks are becoming common, and the software suffers vulnerabilities including theft of the user’s data.
Usually, the security issues are taken care of at the end of the development cycle. However, this approach poses a critical threat. The threat of delays in production releases. If an enormous security shortcoming appears, it might take a long time to fix and can easily delay the deadline to reach end-users. But Cloud makes it possible to assess the security issues during the development iteration. As soon as the code is pushed to the remote repository, it is scanned for vulnerability. If any issue appears it can be fixed straight away hence reducing the time to market.
