With FaaS, you can put your entire focus on individual functions in the application code as these requisites are automatically handled by the cloud-service provider.

In a nutshell, FaaS is a service that eliminates the use of complex infrastructure while executing complex codes associated with crafting and deploying microservice-based applications.

Benefits of FaaS:

If you’re looking to migrate applications on cloud, FaaS is an efficient and cost-effective tool to serve this purpose.

  • Eliminates the worry about infrastructure- Dramatically reduces time-to-market by dividing the server into functions that scales automatically and independently, eliminating the infrastructure management.
  • Pay-per-use- You pay only for the resources you use. Once it’s done, there is no code or server running. This makes FaaS cost-effective even for high-load scenarios.
  • High scaling capabilities- FaaS enables automatic, independent, and instant scaling up or down as per the need. 
  • Availability- FaaS is highly available as it is spread across widely and can be deployed in multiple regions, that too without any incremental costs.

Hybrid Cloud Computing

There is a constant pressure on the organizations for rapid innovations, increase in agility, and process automation for appeasing customers. For the continued survival of enterprises, migration to cloud and leveraging the benefits of cloud services has become imperative. 

A hybrid cloud is a mix of on-premise, private cloud, and third-party cloud services with orchestration between these platforms. Moreover, this IT infrastructure offers application portability to get a unified, scalable, and flexible cloud environment for managing workloads. 

Hybrid cloud is an opportunity for organizations with on-premise infrastructure and that are looking for optimizing operations. The global hybrid cloud market is forecasted to grow at a CAGR of 17.8% by 2028. By leveraging the benefits of speed and flexibility, organizations are all set to resolve the complications and craft a streamlined process.

Benefits of hybrid cloud computing

There are significant benefits of hybrid cloud adoption that organizations are looking forward to leverage.

  • Enhanced productivity- Provisions for Agile and DevOps adoption to enable developers to develop only once and deploy to all clouds.
  • Efficiency- Enables faster migration of legacy applications, reducing the technical load.
  • Cost-effective- Optimizes spending across public and private cloud services and cloud vendors by offering granular control over resources.
  • Optimized regulatory compliance and security- Implementing consistent compliance and world-class cloud security across all the environments.
  • Accelerating business- Hybrid cloud computing offers shorter development cycles. shorter time-to-market, innovative procedures, faster integration, and faster delivery of applications. 

Data security

Today, every organization is planning to get into the bandwagon of adopting serverless architecture for their applications. There is a paradigm shift in the way how the data is secured in serverless applications. This has brought some new challenges to existence.

Visibility- With the adoption of serverless architecture for your applications, there is an increase in the data and resources. This increase in information every day poses a challenge for recognizing patterns and value for true observability. 

Resource Management- With the increase in resources, there is an increase in the permission for managing these resources, further making it difficult to identify permissions for each interaction. 

Observability- To understand the potential areas of attacks and the associated risks, there must be an in-depth view of your entire serverless ecosystem. As serverless apps acquire various services from multiple cloud providers, across different versions and regions, the observability of the application becomes challenging. 

Benefits of serverless adoption for securing your application data

  • Patch management: The adoption of serverless shifts the responsibility of servers, operating systems, and other software components from the application owner to the cloud service provider. The cloud providers patch all the software components time-to-time to protect the software from vulnerabilities. 
  • No compromise with the server: When you work in a FaaS environment, you are unaware of the server assignment for the function execution. The platform provides and rolls back servers as per the need. Once the function is executed, the servers are immediately destroyed. 

Moreover, malicious software needs a lot of time to gain information. With a FaaS environment,  a function is short-lived and stateless, therefore eliminating the server compromisation at any given point in time. 

  • Resistance to (Denial-of-Service) DoS: The DoS attack takes down a server by complying with a large volume of memory-intensive actions. FaaS servers are provided as per the need and then immediately disposed of. This creates a fast-moving target and is difficult to attack. 

Serverless IoT

The area of the Internet of Things (IoT) has undergone a major industry disruption. The global IoT market is forecasted to reach USD 1463.19 billion by 2027 with a CAGR of 24.9%.
