What Is Serverless Computing?
Serverless computing is a method of providing backend services on as needed basis that is enabled by microservices. This contrasts with the early days of computing when developers who wanted to build an application had to have the physical hardware needed to run a server. As a result, a business that switches to serverless computing is gaining more scalability and flexibility at a reduced cost.
Serverless Computing Is A Technological Advancement
The world of technology moves fast. Technological advancements are evolving at lighting speed forcing businesses to adapt or risk obsolescence. One of the more recent technological advancement is serverless computing.
According to research, in 2020, 20% of global businesses will have implemented serverless computing. This adoption constitutes a mindset shift in the delivery and impact of technology services.
The 4 Advantages Of Serverless Computing:
For a business, IT services are a capital expense that needs managing. Therefore, it is lucrative to go serverless and cut costs. Instead of managing physical servers, the business outsources the responsibility of managing servers and databases. Besides a cost reduction, a business experiences savings in computing power and human resources. Serverless computing also saves on the operational expenses of servers crashing. If a business drops a new product to 10,000 users and then 10,000 users go to the website, the possibilities of servers being overloaded, and crashing is high. Consequently, customer experience and revenues suffer. Serverless computing is the solution for this problem.
Use Of Microservices
Another innovative way that serverless computing differs from its predecessor is its reliance on microservices. As opposed to monolithic services, microservices supports serverless computing in making precise application-specific developments and deploying individual applications. In fact, research shows using serverless microservices can reduce the standard release cycle by 75%.
A microservice is a self-contained piece of business functionality that can work independently or together as a whole. Overall, the presence of microservices in serverless computing makes the business more flexible at managing workload. It enables the business to estimate the amount of computing power it needs and not provision the servers upfront.
The advantage of serverless computing is that a business only pays for what it needed. When using traditional servers, a business would have to operate them 24/7. With serverless computing, a business is charged only when the server is used. This makes the business more efficient at managing its resources and eliminates the worry about scaling. The outsourcing of serverless computing also eliminates the concerns about:
More “Green” Computing
Increasingly, technology companies have become concerned about the environment and reducing waste. Serverless computing is sustainable. Servers only run when needed thereby reducing the use of electricity. The lack of physical servers and data centers cuts down on radiation and promotes health.
The research has supported sustainability efforts finding that 30% of servers globally remain unused at a given time. Even further, the physical servers that are in use run at 5%- 15% of total capacity. Serverless computing is not only sustainable but scalable.
All of the advantages of serverless computing indicate that it is a practice that is highly scalable and beneficial for businesses. It is an exciting breakthrough in the world of traditional computing that is gaining momentum. As a result, old ways of doing business are left in the past encouraging businesses to innovate and scale to new heights. Serverless computing is highly efficient, sustainable, and filled with opportunities that take a business into the future.
