Cloud computing architectures and the competitive edge they offer

August 04, 2022

Cloud-based services have flooded the market, and it's no wonder why. They are transforming not only organizations but also changing lives. The shift to the cloud has become crucial for organizations as experts at Gartner predict a 20.4% growth in worldwide spending on public cloud services.

A popular strategy for cloud migration is lift-and-shift. This approach involves migrating applications to a cloud-powered infrastructure without the need for redesigning or disrupting routine operations. Also known as rehosting or Infrastructure-as-a-Service (IaaS), lift-and-shift is a preferred choice by customers and end-users to transition to the cloud.

This blog takes a deep dive into the key differences between lift-and-shift and serverless architecture, providing insights into their features and functionalities.

Understanding serverless architecture

Serverless architecture refers to a cloud application development model that enables developers to build and run code without the need to manage or maintain servers. Despite its name, serverless doesn't mean there are no servers involved.

Instead, it implies that your team will work without directly managing servers. Behind the scenes, cloud-managed services take care of server operations, abstracting the complexities of cloud-native development.

Comparing lift-and-shift with the serverless architecture

When comparing both approaches, serverless computing revolves around the concept of event-driven computing, also known as Function-as-a-Service (FaaS). On the other hand, lift-and-shift is a broader term that encompasses the on-demand usage of cloud services without the need for owned infrastructure.

In technical terms, it involves migrating applications to a temporary infrastructure, typically a virtual machine (VM) provided by a cloud service provider.

Here's a quick rundown of key aspects of lift-and-shift and serverless architecture:

Here's a quick rundown of key aspects of lift-and-shift and serverless architecture: 


· Enhanced scalability: Serverless applications automatically scale as the number of users or usage increases, improving scalability.

· Reduced administration: Since serverless applications don't need to be managed, developers can focus on other important tasks, reducing administrative burden. 

· Foolproof security: Applications transferred to the serverless architecture benefit from cloud security services, making them more secure than on-premises applications. 

· Maximum resource utilization: Serverless applications have no idle capacity, ensuring efficient resource utilization and minimizing wastage.

· Less time-taking: Since lift-and-shift requires no changes to the application architecture or code, it reduces transfer time and minimizes disruptions. 

· Cost-competitive: It reduces the cost associated with managing and maintaining on-premises infrastructure. 

· No capacity planning required: As no on-premises capacity is needed, there is no need for capacity planning.

 · Gateway to improved performance: Lift-and-shift allows organizations to leverage better-performing hardware without incurring additional costs.

Choosing between serverless and IaaS 

End-user spending on public cloud services is expected to reach a staggering $500 billion in the coming years, growing at a significant rate of 30.6%. Cloud-based services are becoming increasingly popular by the day. Whether you choose a serverless architecture for transformation or opt for the lift-and-shift approach to transition to the cloud depends on the specific service you require – whether it is on-demand infrastructure or an event-based cloud service.
