An Overview of Migrating to the Azure Cloud
Benefits of Cloud Migration
Cloud migration can have varying availability, costs, and reliability but the resulting benefits are the key. Not only does it resolve existing data and storage management problems, but the cloud is a proven solution that is only getting better. Here are some scenarios that would benefit from cloud migration services:
- Your data storage needs are constantly growing, thus costing more in upkeep and reliability. In this case, a move to the cloud will allow you to scale storage capabilities with better security and without breaking your budget.
- You would like to lower your operational IT costs while increasing the effectiveness of your infrastructure. Your application is experiencing traffic growth and it’s becoming a challenge to scale resources with the demand to accommodate growth.
- You would like to lower your business IT expense by incorporating a pay-as-you-go model with minimal implementation costs, scalability, and little to no downtime.
Is there a risk in Cloud Migration?
The short answer is - Yes!
Moving to the cloud requires a thorough understanding of what is actually needed. The risks of migrating to the cloud can only be evaluated on a case-by-case basis as each migration requires unique scenarios.
Moving to the cloud requires a thorough understanding of what is actually needed. The risks of migrating to the cloud can only be evaluated on a case-by-case basis as each migration requires unique scenarios.
For example, you already have an existing infrastructure or application setup that meets your needs, requires minimal maintenance, and garners rave reviews from satisfied customers. Why bother to mess with it?
It is also important to consider that once a cloud platform is chosen, it might be difficult to change to another vendor. This stresses my first point which was that a complete picture of the migration plan must be made beforehand that ensures not only your current needs but your future growth needs.
[Note: I will cover how to evaluate your cloud migration needs in a future post]
Cloud Service Model
Once you decide on the cloud, you will need to pick a model that fits your migration needs. The most common cloud service models are:
IaaS: Infrastructure as a Service consists of Container Service and Virtual Machines. These allow you to have control over how you run each service. However, they also require you to be responsible for things like the operating system, security, and load balancing. E
Examples: Azure, AWS, Google Compute Engine
PaaS: Platform as a Service is ready to work on platforms that allow you to run your application without worrying about the operating system. You will still be responsible for some configurations but most services will automatically scale.
Examples: Azure App Services, Azure Search, Google App Engine
SaaS: Software as a Service; with SaaS, you just use the service you need. No need to build it or maintain it. You just need to configure it and manage it. This works great for certain types of apps and tools which you do not need to modify or customize.
Examples: Office365, Google Apps, SalesForce.Com
As you can see, IaaS is best suited for organizations that prefer to outsource their physical infrastructure to a third-party data center. This is normally so that the team can concentrate more on developing, deployment, and monitoring. PaaS is ideal for software developers as it allows control over the application without worrying about the operational side. SaaS is mainly built around productivity tools and is subscription-based.
Cost
Many cloud providers will have pricing calculators that help determine the estimated costs after the migration versus current costs. A tool like Cloudamize allows you to compare costs across multiple platforms. There a number of ways to migrate your applications to the cloud and thus even more ways to implement services without interrupting your current process while keeping costs proportionate to the plan and budget.
Conclusion
I hope this high-level overview of the different elements in cloud migration provided with you with enough understanding of what a well-thought-out cloud migration (such as from aws to azure) can do for your business.
