Microservices online training is related to Kubernetes and containers. In simple terms, Microservices are computer programs that run on virtual or physical computing instances as per the requests of the network. Any organization has a host of Microservices already deployed in the form of Rails, Node.js, Django, and more. To be defined as Microservices, these technologies have to only fit into the broader solution or system to focus on the smaller tasks well. An example of microservices would be the Amazon product listing that has reams of information retrieved from different databases.
What are containers?
Containers in the technical sense are executable files that run on a Linux machine with restrictions applied to them. These containers allow only a designated part of the filesystem to become visible and use minimal CPU or RAM to restrict the use of the network. Any microservices or Kubernetes online training provides knowledge and skills to handle these containers suitably. Tools like Docker help the programmer to create these executable files with all of their dependencies. These containers put all the packages together as a single file for running packaged executables.
Difference between microservices and containers
While containers are a method to pack, deploy, and run Linux processes or programs, the same may be achieved with a swarm of microservices. The containers are a necessary and useful tool to share technology and allocate resources on a network that excites any developer. While the Microservices online training is essentially learning about software design patterns. It is necessary to note here that the microservices and containers are related but do not need each other to function independently if required. One may have a huge single file running as a container or achieve the same through non-containerized microservices.
How are Kubernetes and microservices related?
While Kubernetes is quite complex, it is mainly used to increase infrastructure utilization through efficient sharing of the resources while using multiple processes. The Kubernetes online training provides one the knowledge to dynamically allocate the computing resources as per the demand. It allows organizations to bring down the costs of using computing resources. Thus, microservices that provide autonomy and freedom can interact in the infrastructure properly. It solves the problems of predicting the computing needs, requirement changes under load, enforce resource restrictions and divide partitions between the microservices.
The advantages and disadvantages of microservices
For many decades microservices architectures have been used to decouple applications into their reusable components. The Microservices online training allows a professional to automate testing, deploy flexible models, and improve the overall resiliency of the systems. Adopting microservices also allows one with the ability to pick the best tool to achieve their goals. Some applications may require C++, while others may need JavaScript, Python, or others. The use of microservices also requires an organization to invest more time in planning that may hike the research and development upfront costs. While one has to constantly battle the temptation to over-engineer.
