Serverless Computing – is a cloud computing model in which the cloud provider manages the physical infrastructure on behalf of its client and allocates computing resources on demand (scaling). Serverless Apps are deployed in containers that automatically spin into action when the current assigned resources are exhausted. Examples of popular companies offering cloud computing services include; Google’s GCP, Amazon’s AWS, Microsoft’s Azure, Alibaba Cloud, Linode LLC, DigitalOcean, OVHcloud, IBM. Serverless technologies feature automatic scaling, built-in high availability, and a pay-per-use billing model to increase agility and optimize costs. Most enterprise IT systems nowadays take advantage of “Serverless Computing” technology by running their intensive workloads in the cloud while saving the company thousands of dollars in operation costs and equipment expenditure. The immediate benefits of running your workloads in the cloud include:
- Zero Ops: No need to employ inhouse IT workforce to run and manage your server infrastructure but instead your development team can focus on creating, testing and fast deployment of products and services.
- Inbuilt Security: Cloud providers have invested a lot of resources in research and development to ensure data security for both data at rest (in storage) and data in transit (data accessed over the public network).
- Disaster Recovery: When enterprise firms deploy a mix of private and public cloud, also known as hybrid-cloud, it creates a safety net in times of disaster. In such a deployment, the private cloud works as the primary location with replication to the public cloud as the secondary location. Data can then be recovered from the public cloud should you have any issues on the primary location.
- Saves on development and deployment times. Your team can focus on what is important such as innovation, development, testing, deployment, and lifecycle management.
- Cut down on CAPEX and OPEX: No need for investing in very expensive hardware, and the pay-per-use model also favors companies that have small budgets but want to develop modern-state-of-the-art applications and software.
