Understanding Cloud Migration

Organizations undergoing digital transformations are looking for avenues to modernize, innovate, and adapt their application landscapes to the latest technology available on the big public cloud platforms, such as AWS, Azure, and Google Cloud Platform.

Drivers and Implementation Methods in Business

The key business drivers that trigger discussions on migrating workloads to cloud are:

Innovation: Shifting focus from underlying infrastructure and platforms to application innovation.
Scalability: Unmatched availability, scalability, and agility of cloud resources compared to on-premises deployments.
Cost-efficiency: On-demand usage pattern and pay-as-you-go cost management offered by cloud, converting large CAPEX to smaller OPEX.
Modernization: Alternative solutions to replace end-of-life hardware/software.
Hybridization: Need for hybrid architecture to leverage services unavailable on-premises.
Security: Effective compliance and security management.

Cloud Migration Models: IaaS, PaaS, and SaaS

The process, approach, and tools for migrating workloads to cloud are greatly dependent on the targeted cloud migration models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS).

Let’s take a closer look at each of these migration methods.

IaaS (rehost, replatform)

Moving applications to Infrastructure-as-a-Service (IaaS) involves transferring them from on-premises to a cloud provider’s infrastructure. This method, often via “lift and shift,” requires minimal architectural changes.

PaaS (refactor, rebuild)

Platform-as-a-Service (PaaS) requires significant application refactoring or rebuilding to align with cloud-provider platforms. This includes code rewriting, library updates, and modifying deployment pipelines.

SaaS (replace)

Software-as-a-Service (SaaS) replaces parts of existing workloads with third-party services, requiring architectural adjustments, new interfaces, and data migration considerations.

The quickest way to migrate applications to the cloud is often through IaaS with a lift and shift approach. Explore the benefits and considerations of this method for your application.

Lift and Shift Migration Explained

The lift and shift migration approach involves moving applications and data to the cloud with minimal changes.

Applications are transferred as-is from their current environment to new cloud hosting without significant alterations to architecture, data flow, or authentication methods.

Considerations include matching compute, storage, and network needs from on-premises to cloud resources, optimizing costs by aligning resources and utilizing scalable upgrades for flexibility and maximum ROI.

Choosing a Cloud Migration Approach

When selecting a cloud migration approach, drivers include minimizing disruption, ensuring application compatibility, managing risks, optimizing ROI, and meeting performance and high availability (HA) requirements.

Consider how components interact within the application architecture across interfaces to guide your approach.

Lift and Shift vs. PaaS Migrations

PaaS migrations involve significant application refactoring to fit the provider’s platform, possibly requiring architectural changes.

In contrast, lift and shift data center migration is straightforward and proceeds after analyzing cloud infrastructure support.

Lift and Shift vs. SaaS Migrations

Moving to SaaS involves transitioning application experiences, requiring reconsideration of access controls, data management, and security to align with SaaS structures.

Lift and shift preserves the original application experience and often maintains existing authentication and security mechanisms used on-premises.
