DevOps Trends to Watch in 2017
2016 was great. We have witnessed a great number of technologies and trends in the past year. Like Docker v1.12 was released, AWS got some powerful instances types, and the hybrid cloud (both private and public) became the first choice for enterprises and many more trends.
Here in this blog, I am going to share some latest DevOps trends of 2017.
But first let me give you an introduction to DevOps. DevOps actually the collaboration of Development and Operation team to work together like one unit rather than working the old traditional way which was Agile methodology where the development and operation team worked individually to develop any software or fulfil the services.
The old traditional method was time consuming and lacked the understanding between the team of software development, leading it to customer dissatisfaction.
This is why now we are adopting DevOps as culture for more fast, efficient and reliable software delivery.
Here are some DevOps features
- Maximizes the speed of delivery
- Advances customer experience
- Make use of automated tools on each phase
- Got more stable operating environments
- Has improved the collaboration and communication.
- Enables fast flow for production
DevOps consists of 5 C’s which gives high productivity, less bugs, enhanced communication, provide quick way to resolve issues, more reliability and much more. The 5 C’s of DevOps are:
- Continuous Integration
- Continuous Testing
- Continuous Delivery
- Continuous Deployment
- Continuous Monitoring
Key Trends of DevOps
As the name sounds, microservices is an architectural way to develop the complex applications into smaller modules by division. Microservices can help the developers to decide how to use, design, which language to choose and platform to run and deploy.
Some advantages of microservices are.
- They can be developed in various programming languages
- Errors in any module or microservice can easily be detected saving time.
- Microservice and modules are easy to manage
- Updating anything is easy now. Just push it on the particular microservice or else you have to update the whole application
- Scaling up and down of any particular microservice without effecting any other microservice is now easy.
- Microservice leads to the increment in productivity
- If any of the module is down, the application remains unaffected
Containers create virtual environment, allows to run multiple application or OS without interruption. Through container, one can deploy the application quickly and consistently because containers have their own CPU, memory, network resources and block I/O which shares with the kernel of host operating system.
They are lightweight and can be run directly within host machine. Some advantages of Containers are:
- Easy to share a container
- Manage the lifecycle of containers with the Docker’s platform
- It gives consistent computation environment
- They can run multiple separate application in a single shared OS
The automation, arrangement, coordination and management of containers is container orchestration. Some various features of container orchestration include
- Cluster Management
The task of a developer is limited to launch a cluster of container instances and allot the tasks which are required to run. The management of all the containers are done by orchestration.
- Task Definition
It allows the developer to define the task where they are required to specify the number of containers for the task and the dependencies. More than one task can be launched through single task definition.
- Programmatic Control
Through simple API calls now you can register and deregister tasks, launch and stop Docker containers.
- Load Balancing
Load balancing actually helps in distributing traffic across the containers or deployment.
You can now monitor your CPU and memory usage of the running tasks and also get notified if scaling is required by containers.
There are some tools used for container orchestration (both paid and open source) are Kubernetes, Docker Swan, Google Containers and Microsoft Containers.
It is now clear and evident that 2017 is going to face a lot more changes, new and innovative ways for DevOps.
