Since many businesses have already made the move to the cloud, migrations are currently happening very actively. Why is this tendency so common today? Let's figure it out!

Why businesses migrate to cloud

Businesses are migrating to the cloud for several reasons. Firstly, it brings about lowered capital expenditures. What’s more, it usually results in increased efficiency and a reduction in downtime. If you haven't considered migrating your business processes to the cloud, maybe it's time you start looking towards it.

Why businesses migrate to cloud

As a business owner, there are so many things to be benefitted from migrating to the cloud. Here what you can achieve with cloud migration:

  1. Save time

    Your company can save time in a few different ways by utilizing the cloud. Your team may now rapidly exchange docs when working on projects together and get feedback right away, stopping an email attachment cycle that never ends.

    Additionally, you will get assistance for your use of the cloud and the migration if you are utilizing a support service. You may contact the service team at any time rather than waiting for the IT guy to arrive. In all, using the cloud reduces effort and saves time.

  2. Give your company a competitive edge

    Making a switch to the cloud offers a quick and effective approach to increasing your competitiveness. Regardless of the size of your company, the cloud gives you access to enterprise-class solutions. This makes it possible for companies of all sizes to compete on an equal footing.

  3. Improve data security

    By using the cloud, you can prevent total data loss in the event that a company laptop is stolen or lost since your data is backed up there. Additionally, adopting the cloud minimizes the possibility of data loss or data corruption during server outages or load shedding.

    With the cloud, there are several techniques to ensure the systems or data are only accessible to those who require them. Thus, you can be sure that your data is always secure.

  4. Promote collaboration and remote work

    Thanks to the cloud, employees can easily collaborate on documents, which they can share, view, and edit from any location at any time. Due to recent world events, many organizations were forced to adopt remote working, and online collaboration has since grown to play a significant role in many corporate strategies.

    When you use the cloud, your staff do not necessarily have to be physically present to work together. They can collaborate effectively while working remotely from any location via an internet connection.

  5. Increase flexibility

    Businesses frequently experience varying bandwidth needs, and operating in the cloud lets you downscale or upscale your capacity. Because cloud capacity depends on remote servers and flexibility is a fundamental component of the service, scaling up or down is a lot simpler to accomplish.

    Businesses that are highly agile are not constrained by IT. Hence, they have an edge over rivals since they can sell their products more quickly.

  6. Safeguard your data in case of a disaster

    Utilizing the cloud can assist your company by implementing a cost-efficient and effective disaster recovery plan. Systems and data can be readily transferred and safeguarded using tools and services provided by service providers in a way that best matches your company's disaster recovery plans.

    Examples include complete replication to other clouds (cold, hot, and warm standbys), multiple copies of cloud backups, and cross applications that are load balanced across different clouds.

The stages of cloud migration

Once a database is chosen for migration, the processes of planning, preparation, migration, and optimization can begin. Read about it in more detail below.

  1. Preparation

    The database migration procedure starts with the planning phase. You determine the connections between your apps and databases during preparation. It's also essential to plan your budget according to migration price evaluation that can be done with Azure calculator.

    In order to identify the migration categories—from straightforward rehosting (homogeneous migration) to re-architecting (heterogeneous migration)—you also have to assess the database workloads. Failing to complete this step can cause migration schedule delays.

    Using the 7 Rs of migration (rehost, replatform, relocate, repurchase, refactor, retire, and retain) to organize the data you've gathered is another vital part of the migration planning process.

    Determine your migration strategy based on your organization's objectives for moving to the cloud, as well as any other relevant factors, such as timeline, budget, and resource availability.

  2. Migration

    The actual migration happens once you've finished your migration planning and decided on a migration strategy. This stage involves designing the target database, moving the source data there, and validating the newly transferred data.

    This procedure consists of repeated conversion, migration, and testing phases. You can switch to the new database once the functional and performance testing is done.

    The essential steps of the migration phase are listed below:

    • The schema conversion process
    • Data migration
    • Application updating
    • Migration testing
    • Switching to the new database
  3. Optimization

    As soon as your application is on the cloud, you can begin improving it by utilizing several services that you can activate with just a few clicks. Optimize your application stack in a number of ways, including how it performs, how much it costs, how secure it is, and how well it can withstand failure. For instance, automatic scaling features can be used to minimize costs by adding additional read replicas during peak hours and removing them during off-peak hours. The benefits of hosting applications on the cloud can be used to their fullest extent during the optimization stage.

Approaches to cloud migration

As mentioned above, there are 7 possible approaches to application migration. Here is a brief summary of them:

  1. 1. Rehost (lift and shift):

    This method simply involves moving an application to the cloud. Relocate (hypervisor-level lift and shift): Transfer infrastructure to the cloud without investing in new hardware, updating your software, or changing the way things are currently done.

  2. 2. Replatform (lift and reshape):

    Move an application to a cloud-based environment while introducing some level of optimization to benefit from cloud features.

  3. 3. Repurchase (drop and shop):

    Switch to a new product, usually by changing a traditional application to a SaaS product, and move data from your on-premises application to the current product.

  4. 4. Refactor (re-architect):

    Move an application and change its architecture by utilizing cloud-native features to the fullest extent possible in order to increase agility, performance, and scalability.

  5. 5. Retain (revisit):

    Keep apps in their original environment. Examples of these could be legacy apps that you want to keep running because there isn't an economic justification for moving them or applications that need significant reworking but you want to put off doing that work until later.

  6. 6. Retire:

    Deactivate or delete programs from your source environment that is no longer required.

4 options for moving to Azure

As Blackthorn Vision has extensive experience working with Azure, let’s consider 4 alternate strategies for this service, including their pros and cons.

The most effective methods for moving an app to the Azure Cloud are as follows:

1) Lift-Shift Policy: Using this method, the settings of the underlying applications are not altered while they are transferred from the on-premise platform to the cloud. Teams with minimal cloud computing and Azure capabilities can use this tactic because it is appropriate for legacy migrations.

Pros: With less chance of application failure, this technique enables customers to migrate swiftly and painlessly.
Cons: The application might not take full advantage of cloud resources.

2) Subjective to Code Changes: This tactic merely modifies the application code, leaving out other crucial elements. By utilizing services like Azure App Service, Azure Functions, and Azure SQL Database Managed Containers, the user may reap the benefits of the both IaaS and PaaS. This is appropriate for businesses that are concerned about application scalability.

Pros: This is a speedy approach to upgrading your infrastructure.
Cons: Major infrastructural changes are not possible.

3) Architecture Revamp: This method entails modifying, optimizing, and deploying software to the Cloud platform (which requires high agility, scalability, and resilience).

Pros: Allows you to efficiently and cheaply meet scalability needs. Azure's features can be used by new applications. increased agility
Cons: Migration is complicated, expensive, and there is a considerable danger of errors and service interruptions.

4) Restructure: This strategy entails rewriting apps from the ground up utilizing cloud-based tools like Azure PaaS. This enables the company to obtain whole development and deployment services. This tactic is appropriate when you have apps that are slowing down business processes due to their limited functionality and longevity.

Pros: There is no expensive or complicated software licensing, middleware, or resources to support.
Cons: Custom-made apps will have less functionality overall.
