Have you ever been in the following situations while developing applications?
Have the applications been reconfigured for migration to other platforms? Has the server warranted extra efforts for management?
Let’s get to know more about how Nextlink’s container and serverless solutions can solve such problems!
What is a container and what does it contain?
A container provides a standard way to fit the application codes, configurations, and related resources into a single object. The containers share an operating system installed on a server and make use of the resources as an independent process. Quick, reliable and consistent deployment can be ensured under any circumstances.
The benefits brought about by the container services
To lighten the workload
Every file in a container takes up less space by sharing the same operating system. More resources can be evenly distributed so that the computing resources can be utilized more effectively. Moreover, the containers can be activated more quickly and the services can be expanded further.
Migration to other platforms
The resources provided by container services are interdependent, which means that migration to other platforms requires no reconfiguration but can be executed by direct packaging of images.
Simpler operation of microservices and DevOps
In the structure of microservices, the applications are made of numerous low coupling, small-scale services that can be independently deployed. The software of DevOps Continuous Delivery has to incessantly simplify the application updates, and to switch between different frameworks and platforms. The characteristics of the containers can meet the operational needs of microservices and DevOps.
The container services provided by AWS
Amazon Elastic Container Service(ECS)
Amazon ECS is a completely managed container service. It offers the safest, most reliable, and most expandable format of running containerized applications.
Amazon Elastic Kubernetes Service(EKS)
Amazon EKS is a completely managed Kubernetes (K8S) service. It enables you to run K8S applications in a readily available and safe manner.
AWS Fargate
AWS Fargate is a serverless computing service that can be used in containers. It helps you manage clusters of Amazon ECS and Amazon EKS. It lets you stay focused on developing applications and optimizing costs.
What does it mean by a serverless service?
A serverless service is native to Cloud. The Cloud service providers are responsible for executing a set of codes through dynamic resource allocation. The codes are usually executed in stateless containers, which can be triggered by a variety of events. A serverless service is also known as Function as a Service (FaaS).
The advantages of the simple, easy-to-use, and manageable serverless services
No need to manage servers
There is no need to manage, maintain, install, or deploy any servers. Users can directly enjoy the services.
Cost optimization
The charges are based on the duration and frequency of usage instead of the server units. There are no upfront costs.
Flexible expansion
Serverless services are characteristically available and expandable. As you enjoy the services, there is no need to worry about the capacity, computing power, or other issues.
