Partial or complete migration to the cloud, for companies that want to make big leaps in the journey of digital transformation, is an essential and important first step. Cloud migration is the process of transferring data, applications or other business elements from a local environment to the cloud.
Cloud migration can be done for a number of reasons such as reducing costs, increasing scalability or improving performance, but no matter what, companies need to plan well for their immigration processes to avoid any disruptions at work, and to shed more light on the concept and types of cloud migration, read with us.
What is cloud migration?
Cloud relay is the process of transferring apps, systems and data from local servers to service provider servers, some use the term migrate to cloud to mean Basic "lift and conversion" without the application configuration or basic code modification, to take advantage of cloud features such as automated measurement of computing, storage and networks, others see it as an app tested on the cloud, meaning that basic configuration settings are implemented by the company's technical team, or the cloud engineers contracted to help the applications work better in the cloud environment.
Benefits of relay to the cloud
There are many reasons to move to the cloud, cloud migration can improve your business in the following ways:
1. Increased mobility and response
Cloud migration allows you to respond quickly to new opportunities or market changes.
2. Improved cooperation
Using cloud migration, employees can easily share files and work on projects together from anywhere in the world.
3. Lower costs
Moving to the cloud can save your business money on hardware, maintenance and energy costs.
4. Increased security
Cloud migration can actually improve your security mode by taking advantage of the security features provided by cloud providers.
What are the types of cloud migration?
Complex IT systems must be gradually migrated. Inventory of systems and applications in use is the first step in the development of an actionable cloud migration plan. After that, you must identify certain types of migration to the cloud to be made with each element, which is as follows:
1. Re-hosting ("lift and transfer")
This type of cloud migration is the simplest and fastest way to transfer your workloads and applications to the cloud, with minimal changes to your local infrastructure, it is often used as a first step in migrating to the cloud or to organizations that are not yet ready to reconfigure their applications, and can quickly and without any disruption to your business.
It's a low risk way to move to the cloud since you're not making any changes to your app or workload.
2. Restoration of the statute ("additional lift and transfer")
Restoring the platform is similar to re-hosting, in that it involves transferring workloads and applications to the cloud with minimal changes, however, reinstating the platform also involves making changes to the application structure to take advantage of original cloud features and services, this can include things like increasing or reducing volume dynamically, adding high availability, or automatic measurement.
This type of cloud migration is often used, for organizations that want to update their applications and improve performance, and reinstating the platform can help you improve your cloud applications, making them more efficient and cost-effective.
Also you can take advantage of the features and cloud benefits that can help improve your business, such as automatic measurement and high availability.
3. Reconstruction ("original cloud")
Rebuilding is a more complex type of cloud migration that involves changing both infrastructure, workload structure and your applications, this means rewriting code and redesigning structure, data storage, networks, security, scalability, availability, and more, it is often used for enterprises looking to fully transform their business using the cloud.
The redesigned app is specially designed for the cloud and can take full advantage of its features and benefits, and you can also improve performance, efficiency and cost-effectiveness with a well-designed cloud app.
4. Hybrid Cloud
Mixed cloud is a combination of local and public cloud services with coordination and automation between the two. This type of cloud relay is often used by organizations that want to retain some workloads in the workplace for reasons of compliance or security, while still taking advantage of the cloud's flexibility and scalability.
Mixed cloud gives you the best of both worlds - flexibility and scalability of public cloud, with control and security in workplaces, also you can keep sensitive data locally while still taking advantage of the public cloud for less important workloads.
5. Public Cloud
The public cloud consists of several companies that share the server infrastructure, which belongs to a service provider who is also responsible for operating with them, it is a good option to manage unexpected traffic and increase cost savings.
6. Private Cloud
It is a company-specific server structure, enabling it to be fully customized and adjusted to its needs, giving the company greater control and security, private cloud may generate more cost savings than public cloud in some cases.
How to successfully migrate to the cloud
Cloud migration involves significant changes within the company's business systems and even requires a shift in business philosophy, to successfully implement this relay to the cloud, the various factors that directly affect this process must be taken into account:
Cloud Service Provider
One of the keys to cloud migration, is to choose the right service provider for the company's needs, there are more and more offers from companies (software as a service) and their terms, prices, service types and customer service vary.
It is necessary to conduct a study of the service provider, to know the conditions and review the different important sections such as security or the time of availability of the service.
As in any commercial transaction, a study of the costs of each service for each service provider must be carried out.
Support and Customer Service
When working in the cloud, the responsibility for maintaining all hardware and software lies with the supplier, which is why it is important to look for a cloud service provider with great customer service coverage, with extensive support hours, quick response speed and accuracy that inform accidents.
When using some type of strategy mentioned, prioritize critical-task services for improvement, rebuilding and addressing the rest of your workload with a simple lift and shift, it may also be helpful to start from some low-risk non-critical workloads as a pilot test to help you improve the migration process when you reach critical infrastructure components.
