Are you Migrating Applications to the Cloud?

In these times of uncertainity, businesses are looking to digital leapfrogging to embrace agility, build resilience and future-proof themselves for all weather scenarios. A holistic approach to cloud adoption to realize intended value is easily said than done. This post takes a birds-eye view of migrating applications to the cloud, the strategies involved, how automation can make a difference, the business benefits and how the cloud can be an enabler of business transformation.

What is Application Cloud Migration?

Application cloud migration is the process of moving on-premises or legacy infrastructure to the cloud. It also would apply to moving applications, databases and IT processes from one cloud to another. Moving applications to the cloud would require organizations to review each application architecture, assess its feasibility for the new platform and make empowered choices. It is imperative to take a close look at your application migration criteria holistically factoring in specific compute requirements, resource allocation, business continuity, compliance, security and cost parameters.

Why Migrate to the Cloud?

The cloud has firmly taken root as the definitive destination for digital evolution. The enticing mix of massive computing muscle, unmatched agility and immediate scalability resting on a sustainable cost model is too hard to ignore. The benefits are pragmatic and boundless. In an era of uncertainty and disruption, businesses need to look beyond the horizon. They need to work on an IT system that would create a growth model built on agility, resilience and disruptive innovation. The cloud fits the bill perfectly. The silver lining is all too obvious. A holistic cloud strategy is a natural part of the broader business roadmap, the pivot to an IT transformation plan focussed on tangible outcomes. Cloud computing is here to stay and grow – for enterprises, vendors, brokers, service providers and the entire ecosystem.

What are the Application Migration Strategies

It is very important to have your feet on the ground when looking to shift to the cloud. Your application migration strategy should be tightly aligned with core business goals and also take a deep dive into the environment, the interdependencies, the architecture and current licensing arrangements. The three most common application migration strategies at the broader level are

• Rehosting
• Re-platforming
• Refactoring

Let’s look at each of these approaches in a little more detail.

Rehosting

Also known as “lift and shift”, organizations gravitate towards this approach when there is a need to get the migration done quickly based on supporting business cases. Moving applications to the cloud using the Rehost route is a rapid and smoother migration process with minimal application disruption. It will only require a change to the host configuration since there is new cloud-based hardware in play. A lift and shift context would also entail ruling out cloud-native benefits like continuous real-time deployment. There is also the possibility of sub-optimal performance. Organizations with time and cost constraints or have a lot of commercial or off-the-shelf applications find the lift and shift method a better fit for their business goals.

Replatforming

Also referred to as “lift-tinker-and-shift”, the application or a part is optimized to increase resilience and enhance scalability before moving to the cloud. This approach which is increasingly become popular involves due diligence and analysis. The code is refactored by adopting modern frameworks like APIs and microservices. It might involve transformation from old technology to a new one or code generation for new features needed on the cloud. Optimization allows for faster lifecycles for applications through real-time updates once they are in the cloud. Organizations looking to automate certain defined processes before moving to the cloud are more likely to adopt this migration path. Replatforming is ideal for legacy application modernization and offers the highest TCO reduction possible.

Refactoring

Refactoring is the way to go if you are looking at market competitiveness with major code modifications for enhanced service capabilities, improved performance and speed. It might involve changes in the application architecture and leverage cloud-native features for performance benefits. The disadvantage though is that the more cloud-native the application is, you will be tightly coupled to the cloud you are using. The refactoring route offers greater opportunities for innovation and automation but also comes at higher costs and longer implementation times. Since there are changes to the application at many levels there are a higher probability for errors at the code, configuration and infrastructure levels. It is thus essential to ensure that your cloud readiness assessment is spot on when deciding on the migration journey.

Benefits of Cloud Migration

Cloud computing, adoption, and migration is an essential strategy to accelerate digital transformation at lower costs. In the age of the digital disruptive, businesses with on-premise legacy infrastructures simply cannot afford to lag behind. A holistic roadmap with a differentiated approach aligned to enterprise goals makes all the difference to thrive in a cloud-first world. Being re-born-in-the-cloud today can offer unparalleled benefits as listed down below.

Cloud Migration Challenges

While cloud computing has the ability to unlock deep strategic value through increased business agility, the path towards migrating applications to the cloud is dotted with many challenges. Your strategic cloud migration strategy needs to plan for potential bottlenecks, costs, security and flaws in the implementation process. The primary challenges that needs careful review and clear navigation at a broader level are listed down below.

• Cost evaluation and optimization
• Legacy of technology
• Application prioritization
• Risk Assessment and Security
• Skill gaps and expertise

Application Replatforming with Automation for Cloud Mass Migration

While cloud migration approach strategies work on a horses for courses best-fit model, one increasingly popular approach is application replatforming driven by automation. Automation offers replatforming the highest TCO reduction promise, perfect for legacy systems with substantial returns in migration times and cost savings. Getting on the automation bandwagon can ensure that your application code assessment for refactoring and cloud readiness can be finished in a matter of hours. The entire replatforming journey for legacy applications when using the right automation led tool can be closed in just six weeks while manual methods can take anywhere between six to nine months.

Realize TCO Benefits in your Cloud journey

The most crucial key question that is on top of the mind of every CxO would be TCO savings. Especially in uncertain times when organizations need to keep abreast of twin fold objectives of treading caution and yet unravel opportunities for resilience and growth. Also, different cloud migration approaches have varied impacts on TCO and are aligned to each organization’s unique needs.
