In this article, we put together answers to some of the most frequently asked questions we’ve heard about cloud migration. If you’re new to the matter or consider the idea of moving to the cloud, this FAQ will help you better understand the concepts of cloud computing, cloud migration, as well as its main benefits and challenges.
Cloud computing is the availability of different services, including data storage, servers, software and databases, through the Internet. Cloud computing allows both enterprises and small businesses to minimize or even avoid upfront IT infrastructure costs, make their applications up and running faster, and helps their IT teams flexibly manage resources in accordance with demand, which is often changeable and unpredictable.
In most cases, cloud migration is the process of moving mission-critical operations from on-premises or legacy infrastructure to a virtual data center of a cloud provider, or from one cloud provider to another. It involves migrating your data, applications, databases, and IT processes to remote data centers.
Cloud migration is a great leap towards business digital transformation that changes the way the processes and policies flow.
The cloud is a safe place to store mission-critical data, and now, given the rising popularity of the cloud, it surpassed the capabilities of most on-premises systems in terms of security. The recent pandemic gave a further boost to the even-rising cloud market, so many IT security companies decided to focus their RnD efforts on cloud computing security.
First, cloud orchestration helps ensure data integrity and avoid deployment errors during cloud migration. Then, it offers many important benefits for cloud management: improved optimization, visibility and control, long-term cost savings, increased business agility, and many more.
Now, orchestration is merely a “nice to have” for most companies; however, with cloud deployment and management becoming an increasingly complicated task, it will very soon become a “must have”.
When migrating to the cloud, you should take into consideration such parameters as security, data protection, resilience and availability. For instance, if you feel that you just want to replicate your data in the cloud, you may be good to go with lift-and-shift. Just remember, to ensure the highest return on cloud investment in the long term, you need to choose a cloud migration approach responsibly.
You need to update migration plans every time you change your original infrastructure — this way, you’ll have the same environment on a target side.
Groups are necessary for logical combinations of machines. Association principles can be different: general purpose of machines, geographical location, general rules for storing snapshots and replication schedule. A particularly important and convenient groups feature is the ability to manage common parameters of replication schedule and snapshot storage rules at a time, that significantly simplifies flexible configuration of business application replication.
Setting a replication schedule that deals with a part of IT infrastructure is a complicated task that can be executed with the help of a cloud migration tool, such as Hystax Acura. Settings for schedules and snapshot storage policies can be carried out for all machines as well as for individual groups and individual machines. Detailed overview of this functionality can be found on the cloud migration tool documentation page.
Today, the importance of cloud computing for almost any organization is too high to ignore it. On the other hand, it takes much knowledge of the field to get the most out of cloud migration and to avoid pitfalls. In this article, we addressed the most frequent and critical questions related to the cloud so that you know what to start with – and what should be avoided.
