5R Strategy for Cloud Migration

Cloud migration offers immense benefits to organizations and to name a few are scalability, cost-effectiveness, and increased performance. In this post learn about the strategy built upon 5R which can be implemented by organizations to migrate applications to the cloud.

Gartner, a highly influential information technology research company, describes 5 options for organizations migrating to the cloud. These cloud migration strategies are commonly known as the “5 R’s”.

Developing a Migration strategy

Organizations should not miss out on the opportunity to modernize considering today’s IT ecosystem.  The cloud migration strategy adopted by your organization is the vision of how to move your applications to the cloud.

Every organization has different business requirements and hence will follow a slightly different process in cloud migration. They need to decipher what is in their environment, what are the interdependencies, what is going to be easy and hard to migrate, and how they’ll migrate each application.

Organizations must have a proper plan and approach to migrate each of their application and in what order to do it. A successful strategy will maximize your value from cloud infrastructure while minimizing migration time, effort, cost, and risk.

Let us understand the 5R strategy to migrate applications to cloud:

1. Rehost

Rehost or the Lift and Shift approach. Rehosting is a process of moving your applications from on-premises to cloud environments without modification. This strategy involves minimal risk and effort. It also reduces infrastructure and operating costs. This will benefit the organization in the long-term as it will encourage a cloud-first approach for the company and develop skills within the business.

AWS VM Import/Export, Racemi are few of the tools with which rehosting can be automated.

2. Re platform

Replatform or the Lift Tinker and Shift method which involves moving the applications as it is, with a small amount of up versioning. In this strategy, few optimizations are made before migrating to the cloud, like switching from self-hosted infrastructure to managed services and switching from commercial software to open source.

You may minimize the amount of time you spend managing database instances by migrating to a database-as-a-service platform like Amazon Relational Database Service (Amazon RDS), or migrating your application to a fully managed platform like Amazon Elastic Beanstalk.

3. Refactor

Refactor or rearchitect is a method of transforming non-cloud application into a cloud-native application. It calls for a complete overhaul of an application to adapt it to the cloud. Organizations looking to modify their applications and infrastructure from a monolithic architecture to a service-oriented (or server-less) architecture can use this strategy to boost agility or improve business continuity and maximize operational cost efficiency in the cloud.

4. Retire

While migrating a project to the cloud you might identify applications that are redundant and closing them down can save you on costs. The savings will ultimately enhance the business case, direct your team’s scarce attention to the things that people use, and lower the surface area you must secure.

5. Retain

When a business has highly invested in on-premise applications, or currently has active development projects, or have applications that require high performance, existing applications are working well, organizations that need to comply with strict regulations where the data is on-premise, in such conditions they should migrate when it is required too, otherwise retaining applications on-premise seems a better option.

AgilizTech cloud solution experts can offer a structured 5R migration strategy that can smoothly integrate with any kind of cloud deployment – be it public cloud, private cloud, hybrid cloud, or multi-cloud.

Extended Team Model

What is Extended Team Model?

Extended Team Model (ETM) is a form of outsourcing strategy wherein the offshore in-house team is augmented or extended by a virtual team of developers. The key competency remains with the core in-house team and any skill gaps in the core staff are bridged by the extended team.

How ETM is different from other models?

  1. ETM complements the in-house staff, rather than replacing it. It is aimed at filling the gaps in expertise of the core team to enhance its overall potential.
  2. The responsibilities are distributed evenly among all team members in the in-house and offshore team. All the team members are equally responsible for the success of the project.
  3. It’s not necessary that the extended team is dissolved after the project is completed, rather they may be considered for long-term collaboration.

 

Key Benefits of ETM

1. Efficient team work

Extended Team model enables dynamic development process and the team has greater synchronisation since all the team members are on the same page. The team members directly communicate with each other, and this eliminates the middlemen, resulting in streamlined communication.

2. Increased transparency and control

The company has complete control over the processes as the extended team is incorporated into the in-house team. The teams share unified repositories for source code control and bug tracking, which gives the client or the product owner complete transparency and updated information on the project development.

3. Shared accountability

Increased synchronisation between the teams leads to shared responsibility and accountability for the overall quality of the project and promotes a collaborative approach.

4. Improved scalability and agility

ETM allows the company to scale the team depending on the current project needs, without having to deal with recruiting and other administrative work. It helps to add team members, while enabling the company to focus on its core business needs. At the same time, it enables the project teams to respond better to changing customer needs, hence improving the agility of the project team.

5. Best talent and motivated developers

The developers are assigned to the project full-time and the team members are highly motivated, working towards a common goal.

6. Cost savings

Adopting ETM results in substantial cost savings for the company, as it helps to choose from an international resource pool according to the desired skills and rates. It also avoids spending effort, money and time in the continuous recruiting and training of staff.

Thus, ETM provides an easy start with high scalability and enhanced effort cohesion in the team, as well as a faster time-to-market for new products. However, this model requires good and clear communication between the team members and the various communication channels must be identified and kept open always.

 

When should you consider ETM?

  1. It is the most convenient option when your own in-house team already has developers, but there are some limitations in the in-house talent pool.
  2. Ongoing projects that expand gradually over time and substantial manpower is required to maintain.
  3. Long-term projects with an evolving set of requirements wherein the required technologies are not available.
  4. Projects which have secondary projects within them, and you prefer the extended team to work on the secondary projects, so that the in-house team focuses on the main project in core business.

 

Is Extended Team a good option?

Extended Team Model can be considered as a reliable go-to outsourcing model when you want to scale your in-house team of developers efficiently. We, at AgilizTech, can help you to expand your team with a hassle-free setup and take care of all operational tasks.
