Why Dependency Discovery and Documentation is Vital for a Successful Cloud Migration Strategy

Posted by Brenda Barrioz on Nov 20, 2019 10:55:47 AM

Despite its already wide-scale adoption, the growth of cloud computing continues to surpass expectations in enterprise usage.

 

Public cloud revenues are expected to grow by 17.3% in 2019, with the IaaS industry (Infrastructure-as-a-Service) experiencing a similarly explosive 27.6% increase, according to Gartner research.

 

Unfortunately, migrating to the cloud is still a challenge for many organizations. Moving enterprise workloads to the cloud is not as easy as it should be. Most—if not all—modern applications have numerous interdependencies that complicate cloud migration tasks significantly.

 

Without having a clear understanding of these dependencies, organizations lose valuable time and money to botched cloud migration efforts, which is simply not acceptable in today’s hyper-competitive markets.

 

What are the challenges organizations face when moving to the cloud and how does dependency mapping help overcome these issues?

The Main Challenges Enterprises Face in Cloud Migration

As mentioned earlier, enterprise cloud migration is a complicated task even for well-equipped organizations due to the many business-critical applications and vital data involved.

 

Enterprises must ensure the migration process is as painless as possible to prevent costly IT disasters during the migration process. That goal begins by overcoming these three key challenges:

1. Planning the Right Strategy to Mitigate Cloud Migration Risks

Proper and extensive planning is critical to any major IT project, including cloud migration. Organizations face the tough challenge of choosing the best strategy to migrate to the cloud. For instance, should they consider rehosting, replatforming, or refactoring? This is just one of the many concerns related to cloud migration planning.

 

Another important aspect of a successful migration strategy is choosing the right applications to relocate. A common mistake is to migrate applications that don’t work well on the cloud, resulting in inefficient cloud usage. In fact, organizations waste 35% of their budgets on resources that provide little to no business value—one of the negative impacts of poor application migration planning.

2. Unexpected Cloud Migration Costs

Speaking of wasted resources, organizations are often caught off guard by the hidden costs of cloud migration. This is a common problem in lift-and-shift approaches, where organizations replicate their existing IT infrastructure on the cloud without making any optimizations or tweaks. This leads to overprovisioning, which spikes migration costs unnecessarily. The larger the existing IT architecture is, the more expensive cloud migrations will be, naturally, since larger amounts of data and numerous, non-cloud optimized applications will require more effort. Of course, the more complicated the system, the harder it is to predict costs.

3. Poor Application Dependency Visibility

For a cloud migration strategy to succeed, IT teams must understand the dependencies of every asset to ensure the system works as expected after migration. When developers don’t have clear visibility of dependencies in IT environments, it can cause major problems in the migration chain, including system outages and broken applications.

 

Why is this a problem?

Enterprise applications have tons of interdependencies and external dependencies for important resources like OSs and middleware. This dependency chain becomes much more intricate when organizations migrate to the cloud, as they now have to factor in the dependencies of each cloud tool or service in use. If a cloud asset breaks down, it can take teams weeks or even months to find a solution, leading to disruptions in business operations, which ultimately affects revenue and customer trust. Thankfully, all of the challenges above can be solved by utilizing a code dependency mapping tool.

What is Code Dependency Mapping (CDM)?

A CDM tool gives businesses total visibility and documentation into every asset and interdependency of enterprise IT environments, including applications, servers, networking assets, and more importantly, unknown dependencies. All dependencies between services and components (including in cloud environments) are tracked and analyzed so organizations know how a change will affect dependencies. This allows enterprises to execute successful cloud migration strategies and mitigate the challenges of poor visibility, hidden costs, and uninformed planning.

 

CDM works at the code level, which gives developers a deep look into the inner workings of enterprise IT systems. A major benefit of code-level mapping is that cloud teams can assess technical cloud migration decisions—both minor and major—and understand their impacts without actually implementing changes. This eliminates unexpected downtime and bugs when dealing with application migration, while also providing cheaper, more secure, and more successful cloud migration strategies.

Advantages of Code Dependency Mapping for Enterprise Cloud Migration

Migrating enterprise workloads to the cloud is risky without understanding the critical dependencies of IT environments. There is a high chance of cloud migrations going wrong without engaging CDM tools beforehand, as applications may break or vital data may fail to integrate along the way.

 

A CDM tool prevents cloud migration errors by visualizing every application dependency so developers can detect and discard changes that will break enterprise systems. This enables fault-free cloud migration strategies, thus allowing organizations to benefit fully from the cloud.

 

The other important benefits of CDM for cloud migration strategies include:

  • Identifying business-critical components and dependencies in cloud and on-premises IT environments
  • Reducing bugs and errors in migration strategies (e.g. rehosting, replatforming, etc.)
  • Identifying weak or vulnerable areas which can be improved to increase cloud performance and assist with disaster recovery measures
  • Identifying data and server clusters to help with containerization and other cloud optimization practices
