According to Gartner, more than $1.3 trillion in IT spending will be affected by the shift to the cloud by 2022. Cloud infrastructure has numerous advantages compared to traditional on-premise systems. In order to remain competitive in this shifting market, the question is no longer if you should migrate to the cloud, but how.
Gartner has identified five common strategies for a successful cloud migration, dubbed the 5 Rs:
Each strategy has its own advantages and drawbacks, and deciding which is right for you is an important decision.
Rehosting is also known as “lift and shift”. Among the five strategies, rehosting can be one of the fastest. It has the possibility of providing immediate benefits and can save you up to 30% of your operational costs before optimizing your apps for cloud deployment. Numerous tools, both automatic and manual, exist to facilitate this strategy.
While this method can provide significant cost savings allowing you to see immediate results, some applications can be especially difficult to lift and shift, and certain types of applications might not be scalable.
Refactoring is also known as “re-architecting”. This approach requires a complete reengineering of the logic of the application for migration in order to fully leverage cloud-native services and features. This may take place within the application’s code, its architecture, or both.
Some of the disadvantages of this strategy include framework lock-in and possibly missing capabilities. The two major disadvantages however are that, of the five strategies, this strategy can be one of the most expensive and time-consuming.
However, at the end of this process, you will be rewarded with a highly scalable and robust application which will help to reduce your time to market in the future.
Revising is also known as “re-platforming” and has also been called “lift, tinker and shift”. This strategy involves two steps. The first step involves making changes to the application and exchanging some of its components with cloud services. For example, you may elect to use a new cloud-based database system or a change from a proprietary to open-source webserver. The second step is to then rehost or refactor the application.
Although this strategy will cost more than lift and shift and require in-depth testing, it can help you to more fully leverage cloud services while reducing operational overhead.
Rebuilding is perhaps the most involved of the five strategies. As its name suggests, this strategy requires discarding the application’s current code and completely rebuilding the application to run on cloud platforms.
Since the application is being completely redesigned, this gives you the opportunity to completely modernize and customize the application, as well as the ability to fully leverage the latest cloud-based solutions. On the other hand, it will also force consumers to make the switch to your new application, so you will need to redefine your SLAs.
Replacement, or “repurchasing”, refers to the strategy of simply discarding your current application and replacing it with a commercially available option. It will limit customization and might lock you in to a particular vendor, but it is very cost-effective with very immediate results.
Choosing which strategy is right for your business is not an easy decision. In order to help you choose the best strategy, you may wish to consult with an application migration consulting firm such as Trianz.

What Is an SQL Query Engine? SQL query engine architecture was designed to allow users to query a variety of data sources within a single query. While early SQL-based query engines such as Apache Hive allowed analysts to cut through the clutter of analytical data, they found running SQL analytics on multi-petabyte data warehouses to be a time-intensive process that was difficult to visualize and hard to scale.Explore
A Winning Base for Successful Digital Transformations When it comes to developing a successful digital strategy, it is not just corporations planning to maximize the benefits of data assets and technology-focused initiatives. The Government of Western Australia recently unveiled four key priorities for digital reform in its new Digital Strategy for 2021-2025.Explore
Engage Your Workforce with a Modern Employee Intranet Solution The employee intranet has changed significantly since it was first introduced in the early 1990s. What started as HTML-based static portals have now evolved into intuitive communication tools complete with search engines, user profiles, blogs, event planners, and more. Today, many organizations are taking a second look at employee intranets to bridge gaps between teams, build company culture, centralize information, increase productivity, and improve workflow.Explore
Adopting emerging cloud technologies, consolidating resources, and improving processes is the key. “IT no longer just supports corporate operations as it traditionally has but is fully participating in business value delivery. Not only does this shift IT from a back-office role to the front of business, but it also changes the source of funding from an overhead expense that is maintained, monitored, and sometimes cut, to the thing that drives revenue,” said John-David Lovelock, research vice president at Gartner.Explore
Deliver Powerful Insights Instantaneously with Federated Queries - No Matter Where Your Data Resides The concept of federated queries isn’t new. Facebook PrestoDB popularized the idea of distributed structured query language (SQL) query engines in 2013. Over the years, AWS, Google, Microsoft, and many others in the industry have accelerated the adoption of a distributed query engine model within their products. For example, AWS developed Amazon Athena on top of the Presto code base, while Google’s BigQuery is based on Cloud SQL.Explore
What is Unstructured Data? Almost 80% of the data that enterprises and organizations collect is unstructured - data without a set record format or structure. Unstructured data includes data such as emails, web pages, PDFs, documents, customer feedback, in-app reviews, social media, video files, audio files, and images.Explore
