According to figures by Grand View Research, the global DevOps market will be close to $12.85 billion by 2025, with a CAGR of 18.60%. Statistical data demonstrate the growing spread of DevOps culture.
Let's take a look at six main DevOps development trends, which are shaping the future of this culture:
1. More attention to automation.
DevOps is becoming the industry standard for many enterprises. According to Atlassian Survey 2020, 61% of companies that have adopted this culture have observed improved software quality, 49% have reported faster time-to-market, and 49% are enjoying increased deployment frequency. These statistics demonstrate that DevOps is a crucial part of a successful business plan.
Although automation is included in almost all stages of the software architecture development life cycle (planning, development, testing, deployment, and monitoring), work doesn’t stop there. The latest tools in DevOps presuppose automation.
Torsten Volk, Managing Research Director for DevOps Containers at EMA, assumes that optimizing the work will require AIOps - Artificial Intelligence for IT operations. This will allow us, in the future, to fully automate the DevOps process with maximum business value, taking into account rapidly changing corporate requirements.
2. Coding skills will become a must for a DevOps engineer.
In 2018, the number of LinkedIn vacancies for the query “DevOps Engineer” accounted for 74,834. This indicates a heightened interest of companies in such specialists. As of 2020, 69% of organizations had their own DevOps team, and 49% had hired one or several DevOps engineers for this purpose. Notably, recruiters believe that the ability to code is considered a basic skill in the list of the six important skills this specialist must have. Today, it's hard to imagine a DevOps specialist who doesn't know at least one programming language.
3. Focus on security implementation.
Security is of key importance for any DevOps development company. Detection, fixing, and prevention of vulnerabilities and faults occur before the product enters the production environment.
With the speed at which new iterations are released, maintaining software reliability can be difficult. As practice shows, more than half of companies are reducing the number of security measures in order to meet the deadlines.
The global hack of Uber proves that sacrificing security for the sake of speed isn’t worth it. As a consequence of attacking the system, the personal data of 57 million taxi users were stolen. Hackers stole the names, emails, customer phone numbers, and ID numbers of 600,000 of the company’s drivers. Uber was forced to pay cyber criminals $100,000. Nevertheless, information about the hacking came to light, and the management had to work hard to save their reputation.
To prevent such situations from happening, DevSecOps - a combination of security and privacy - comes into play. This solution offers protection against new types of risks discovered during CI/CD implementation as part of DevOps testing.
Security checks take place during the coding process. DevSecOps includes code analysis, automated security management tools, and post-deployment tracking. DevOps engineers detect and fix issues before launching, which gives users more reliable software.
4. The need for a microservice architecture will increase.
Microservices are an architectural style where an application is presented as a set of loosely connected services. They are often equated with DevOps. Netflix, PayPal, Amazon, eBay, and Twitter are just a few of the companies using microservices today.
Of course, there are many cases where monolithic architecture is more than justified - for example, in relatively small projects. One needs to learn to understand when it is easier and better to use monolithic architecture and when the application has grown to a scale that requires splitting it into microservices.
5. CI pipelines will be replaced by DevOps Assembly Lines.
The future of DevOps is shifting from CI pipelines to assembly lines. As we know, CI stands for continuous integration. A classical CI pipeline includes three stages: building, testing, and deployment.
DevOps Assembly Lines are focused primarily on automating and integrating activities carried out by multiple teams. These are CI for Devs, configuration management for Ops, test automation for Test, security fixes for SecOps, and so on.
The CI pipeline deals with one action on the entire assembly line. If we split a project into a chain of blocks, there will be a pipeline full of different actions. Each pipeline is assigned to an individual team that needs to interact with other process participants.
6. Serverless technologies will provide flexibility.
More and more professionals are realizing the benefits of working with serverless technologies.
Serverless computing doesn’t mean the absence of a server - machine resources are allocated by the cloud provider. It turns out that multiple decentralized application services are published in cloud storages. The important part is performed in the cloud, and the client side is responsible for delivering the result to the user and conveniently managing the process. Such architecture makes you think not of microservices but micro microservices because each function is located at its own address.
The serverless approach frees engineers from working with the infrastructure and the server. Scaling can occur automatically with an increase in the load on a particular component, but sometimes you still have to optimize the code.
A controller associates the logic with the display and is implemented in the client application. From the controller, specific functions are called, and work with a remote database is carried out. In this case, you don't need to make any requests at all, just initially sign a new client. This frees up time to focus on building better apps. Therefore, companies using serverless computing for DevOps will eventually achieve more flexibility.
