Cloud Migration Strategy: Key Elements

Many offices today have switched to remote work, which led to the popularization of cloud technologies. And if you, as a business owner, aren’t using them yet, it’s high time to change tactics and start doing it.

In our new article, we’ll discuss key reasons for cloud migration and outline the best way to approach this process.

Migration means the transfer of a company’s IT infrastructure to the capacity of a virtual data center owned by one of the third-party cloud hosting providers. IT infrastructure includes various data, any services, applications with their settings, corporate mail, business documentation, customer contacts, etc.

The companies that usually recourse to strategies for cloud migration are the following:

  • organizations whose activities cover several geographic locations;
  • large companies with too complex and multifaceted IT infrastructure;
  • businesses with seasonal surges in purchasing activity. Cloud technologies help them cope with peak loads;
  • companies expecting rapid growth of their customer database. The cloud environment allows scaling the resources used in a more efficient way;
  • SMB representatives or startups with a limited budget. They find it more cost-effective to use cloud solutions;
  • offices working remotely (and there are a lot of them, due to the pandemic).

There are a number of large providers on the market today, including Amazon, Microsoft Azure, Oracle, and others. These companies are responsible for cloud services and guaranteeing their availability, reliability, security, scalability, etc.

Statistics

  • According to Flexera’s 2019 report, nearly 95% of business owners use some kind of cloud solution (it is about any use, not just full data transfer). And this figure has increased even more since the start of the pandemic;
  • As recent research shows, cloud hardware sales have grown 34+% in the second half of 2020 (compared to last year);
  • 65+% of companies have a dedicated team of cloud experts, and over 20% of organizations plan to create one;
  • Oracle predicts that 80+% of business applications are likely to migrate to the cloud over the next decade.

Top Reasons for Cloud Migration

The main benefits of the cloud environment and its usage include:

  • Cost savings. You don’t have to buy expensive server hardware and spend money on its maintenance, which leads to cost savings of up to 50%.
  • Flexibility. By saving on hardware, you also gain additional flexibility when scaling your business. Simply put, you can improve your project according to your needs and safely enter new markets.
    • Previously, you could be stopped by the fear your equipment wouldn’t cope with peak loads, now this problem is a thing of the past.
  • Clear pricing. Your expenses will be logically justified and quite reasonable, you’ll pay only for the service received, nothing more.
  • Ease of cloud-based infrastructure maintenance. A few employees are just enough to make the cloud system work at the proper level, whereas before you had to maintain a whole staff of experts.
  • Fast implementation. The cloud migration process takes a minimum of time, which is also a great advantage.
  • 24/7 support. You get 24/7 support. Do you have any questions or, God forbid, problems? Contact the specialists anytime, anywhere, and if your choice of provider was correct, you’ll receive help in the very near future.
  • Widespread availability. Access to cloud services is available around the clock. The information is being constantly synchronized and updated, and you have the opportunity to work anywhere in the world at any time using any device.
    • Under quarantine conditions, such availability simplifies the transfer of company employees to remote work.
  • Enhanced security. Later in the article, we’ll discuss cloud migration security risks and ways to avoid them. And right now, we just say that reliable providers would ensure the protection of your corporate data.
  • Data backup. And speaking of data, let’s not forget another advantage of cloud systems, namely, backup. The risk of data loss is less than 1%, which means you’ll be able to recover your information if needed.
  • Regularly updated cloud technologies. Again, if you’ve made the correct provider choice, you’ll get a service, which is constantly evolving and being supplemented with new cool features. After all, these companies focus on offering the most innovative solutions.
  • Less risk of service downtime. Of course, no one is immune to such problems, but cloud hosting providers do their best to solve them as quickly as possible. Among others, they invest a lot of money and effort into increasing the fault tolerance of their equipment. Because let’s face it, they’re interested in ensuring that client resources work smoothly and without interruptions.

Types of Clouds

  • Public clouds. The meaning, we think, is clear: these cloud systems are being delivered to a large number of users, and your company is one of many.
    • You should choose a public cloud if your main goal is business management flexibility and task automation;
  • Private clouds. If the first option doesn’t suit you, you can create your own cloud-based infrastructure. This isn’t a cheap way to go, but, in some cases, the game is worth the candle.
    • Choose a cloud migration strategy of the private type if you own a large business with complex IT infrastructure or deal with highly sensitive data.
  • Hybrid cloud environment. The third option is a compromise and lies in the fact that you serve the bulk of your resources on your own, and a third-party data center is just а supporting one. Its task is to allow expanding and developing your business with greater comfort and less risk.
    • Imagine your app or website has had an unexpected success, and it resulted in the influx of a large number of new customers. Of course, you must be prepared to handle peak loads. In theory, a public cloud could help you… but what if you’re working with extremely delicate data that you don’t want to risk? Then you had better resort to a hybrid model when you yourself choose the components to exist in the public cloud.

3 Basic Cloud Migration Types

  • Local data storage is becoming cloud-based. It’s about moving data stored locally to the cloud. The benefits of such data movement have been explained earlier in the section devoted to the top reasons for cloud migration.
  • Reverse migration. Sometimes it becomes necessary to do the opposite of the above and move the cloud-stored data to the on-premises environment. The need to migrate to the cloud is clear, but why move data back? Reasons may include wanting more control over corporate digital infrastructure and the like.
  • Сloud-to-cloud transfer. The last item on our list is migration from one cloud provider to another (if the latter offers more favorable cooperation terms).

Amazon is one of the most renowned cloud providers. Follow the link and read our article on its benefits.

We’ve figured out the backbone of the issue, now it’s time to get into the details. And above all, we have to discuss a plan for migrating to the cloud (or rather, a cloud migration strategy).

Key Strategies for Cloud Migration

  • Full migration, when you move all your infrastructure to the provider. In return, you get special terminal stations to access your services.
    • Prepare to find some time (at least a few days) to perform a full migration.
  • Partial migration. Basically, this is a variation of the hybrid model we mentioned earlier. To be precise, you transfer only a part of your systems to the cloud, a share of your IT infrastructure remains at your facilities.
    • Usually, partial migration is needed as testing of chosen cloud technologies, a kind of initial stage of a full-fledged migration of all your resources.
  • Optimization-enhanced migration. In this case, you’re not only migrating your systems to the cloud but also transforming and optimizing them to be able to take full advantage of the cloud-based infrastructure.

So, there are three basic migration strategies; which one to choose in your particular case?

Firstly, let’s say that optimizing resources when migrating them is always a good idea. But what about full and partial IT infrastructure transfer? What is better and why?

  • If you are a small or medium business owner, you can safely choose a full data migration.
  • If your company is large and complex in its infrastructure, the best option is to use the principle of cautious gradation, so to say. Act by phases, don’t move all your data at once (to be precise, select a partial migration model).

Rules for the Successful Use of Cloud Migration Software

  • Maintaining business continuity. You should maximize seamless data migration to minimize or even prevent downtime.
  • Meeting your expectations. You shouldn’t migrate to the cloud out of a blind desire to follow a newfangled trend. To achieve great results, you must analyze your business situation and determine what your company needs, to begin with.
  • Starting small. Take your time and act gradually if you’re not 100% sure you have made the right decision.
  • Paying attention to licensing. Before initiating the cloud migration process, you must carefully review the proposed cooperation terms and make sure they meet your goals.
  • Considered automation. You should automate the migration process whenever possible. Your task is to simplify and optimize your business, to make management of the company easier, and not vice versa.
    • There’re many cloud migration tools to help you with this, such as the Amazon Server Migration Service (and others of the same sort).
  • Monitoring and analytics. You must constantly monitor the progress of your resources hosted in the cloud, which means you need special statistics and analytics services (including Google Cloud Monitoring, Amazon CloudWatch, and Azure Monitor).
