Cloud hosting in India has blown up in the last few years. It is considered as a natural next step in the transition to infrastructure as a service. With big brands such as Coca-Cola going serverless, it’s getting a lot of traction for its ability to help companies achieve new levels of speed and scale in building applications. Let’s discuss what exactly severless aka Cloud computing means!

What exactly is Cloud Computing?

An extraordinary sort of programming design in which the execution of use rationale is done in a situation without the requirement for virtual machines, servers, working frameworks or visible processes is termed as “serverless”. This kind of environment actually runs on top of an OS and utilizes virtual machines or physical servers, but the responsibility for managing or provisioning the infrastructure belongs completely to the service provider. A software developer, therefore, focuses on writing the code. In other words, he thinks in terms of functions or services that establish communication with each other and the external world. Basically, cloud hosting gives the power to the developer where they don’t have to care about IT operations.

Benefits of going Cloud!

1. Decreased time to market: It gives developers more time to build new apps. Rather than taking months to build an application, now they take few weeks.

2. Enhanced Scalability – Everyone wants his app to be the next popular one like Instagram and Facebook. But the concern is if it happens, can it handle the load? With the cloud, you don’t have to worry.

3. Lower cost: Cloud consumes less computing power and low human resources, resulting in cost saving.

4. More time for user experience: Users don’t care about the infrastructure; they care about the features and experience. Cloud allows teams to focus resources on the elements that keep users happy.

5. Enhanced latency and geolocation: An application’s capacity to scale relies upon three things: its number of clients, those clients areas, and system idleness. Today’s apps have global audiences, which can create latencies that diminish experiences. With cloud hosting, providers have points of presence near every user, and apps perform equally well for everyone.

From photograph sharing applications to cultivate information dashboards to associated fly motors, the cloud can oblige the far reaching needs of application engineers.

Drawbacks of going Cloud!

1. Vendor lock-in: Vendor control, multi tenancy problems, vendor lock-in, and security concerns are some of the problems due to the use of third-party APIs. Surrendering framework control while actualizing APIs can prompt framework downtime, constrained API redesigns, loss of usefulness, unforeseen points of confinement, and cost changes.

2. Lack of Operational tools: The developers are reliant on vendors for debugging and monitoring tools. Debugging distributed systems is difficult and usually, requires access to a significant amount of relevant metrics to identify the root cause.

3. Infrastructure Complexity: Cloud architectures introduce additional overhead for function. There are no “local” operations; you can’t assume that two communicating functions are located on the same server.

4. Usage Drawbacks: Integration testing cloud applications is extreme. The units of integration with cloud FaaS are a lot smaller than with other architectures and therefore we rely on integration testing a lot more than we may do with other architectural styles. Problems related to deployment, versioning, and packaging also exist. You may need to deploy a FaaS artifact separately for every function and there’s no concept of versioned applications so atomic rollback isn’t an option. You may need to kill whatever occasion source is setting off the capacities, convey the entire gathering, and afterward turn the occasion source back on is intense.

If you ask me whether to adopt cloud, I would say it purely depends on your need. While this technology is still growing, it is not meant for every organization. These are four scenarios where your company can benefit from cloud:

• You need a scalable environment
• You are already using the AWS ecosystem and tools.
• You want to cut costs and reduce the need for server management.
• You are developing a new project.
