Auto-Scaling of Micro-Services Using Containerization

Cloud computing has emerged as a new computing model, where storage, network and computation is provided as a service to user, who can lease and release the service on demand. To enable the user of cloud environment to develop and deliver solutions, the cloud provider has to build a robust set of services to support the customers. These are Platform services. The cloud service provider has to adhere to strict customer (Service Level Agreement) SLAs. To support these SLAs, platform services need to be built with certain principles. We present an approach of restructuring platform services into micro-services. These micro-services are nothing but loosely coupled and independently deployable services. Deployment of service in cloud needs to be dynamic. You need to deal with failure cases and provide high availability. It is required to manage more instances of application when the demand increases and to scale down for fewer requests for conserving energy. The traditional use of virtual machine to deploy services lead to low performance. OS level virtualization approach is adopted to deploy services. Here we have proposed an approach for elastic scaling of services in cloud environment.
