• Responsive technology usage

Cloud migration improves flexibility, allowing developers to suitably combine operating systems, web platforms, programming languages, and databases as needed.

• No vendor lock-in

There’ll be no need to stick to a certain cloud provider if it doesn’t suit your business. You can work in any cloud and transfer between different ones.

• Accessible infrastructure administration

Cloud-native apps are easy to maintain since they have microservices that can be updated due to the extension of the application functionalities.

• Failures resilience

Since cloud apps can automatically process failures, they are resilient to any breakdowns by nature. You can effortlessly provide some updates without disrupting the end-users. 

What Is a Cloud Service Provider and How to Choose One

You might need a place to store all your data, run applications, have databases, or even need computing power to handle different tasks, but buying and managing your own servers and data centers can not only be very overwhelming but also very expensive. A service cloud provider lets you use their powerful computers, big storage spaces, and software over the internet.

Even if there’re more than 100 cloud service providers, we all know the leading ones: AWS, Azure, and Google Cloud. However, notwithstanding that Google Cloud and Azure appeared on the market a few years later after Amazon Web Services, they have quickly adapted and created decent competition for AWS, becoming reliable cloud providers both for small and large businesses. 

Here’s what you should know about each one to help you make a more informed decision:

• Azure cloud services

Azure is a Microsoft solution that seamlessly integrates with Windows, VBS, SQL, databases, and Active Directory. It offers a big range of services, such as computing, networks, security, and many more. You only pay for the used resources on a minute payment basis, making it more cost-effective for those who have already invested in the Windows ecosystem. Azure also supports hybrid solutions.

• Amazon Web Services (AWS)

AWS is one of the largest cloud providers, known for its secure environment for cloud computing. They offer a range of instruments, from internetwork monitors and endpoint protection to vulnerability scanners. AWS excels in scalability and supports hybrid solutions.

• Google cloud computing services (GCP)

GCP is best known for its security and low prices. GCP ensures protection from the physical infrastructure to operational processes. Pricing is based on pay-per-minute billing. The hybrid cloud support was introduced in 2018, strengthening the focus on multi- and hybrid cloud workloads using Anthos.

To get rid of any hesitation you may have regarding the choice among three of these, let’s have a closer look at the detailed table.

It’s not hard to notice that there’s no total winner. All three create a secure and effective environment with their special capabilities. Again, all the technology-related decisions depend on the exact business needs and state of the market. 

Step-by-Step Migration Strategy From On-Premise to Cloud

A successful cloud journey consists of three stages: discovering, planning, and executing. In this section, we’ll go through each one, showing you how and what needs to be done in each of the three stages.

1. Define Current State

The cloud migration journey begins with identifying current inventory assets and deciding which one to migrate to the cloud, which not to, and which ones need fixing.

• Identify all your hardware, software, and data currently in use and determine which application and data you want to migrate to the cloud.
• Set and clarify your objectives, such as the purpose of the migration.

2. Plan

Once you have all the theoretical parts in place, we can move on to developing a more practical plan that you will follow along this process of migrating from on-premise to cloud.

• Choose a Cloud Service Provider (CSP) that fits your needs and goals (use the last section as guidance).
• Set and clarify your objectives, such as the purpose of the migration.
• Choose a cloud deployment model (private, public, and hybrid).
• Set clear expectations of your estimated budget and timeline for the entire migration process.

3. Develop a Migration Strategy

This step is all about deciding on which migration approach to follow. This can vary from Lift and Shift, Refactor, Replatfrom, Repurchase, Retire, and Retain.

• Take some time to research each specific migration approach to gather as much info about each one.
• Determine which approach is best for migrating your specific applications and data.
• Develop a detailed migration roadmap that includes each part of your migration process, such as the timelines, resources, and requirements for each step of the process.

4. Conduct a Data Modeling and Architecture

Design your data architecture in the cloud and perform data modelling to make sure all your data is organized, secure, and easily accessible in the cloud.

• Decide and create data warehouses, data lakes, or even both depending on what suits your needs best.
• Create a well-structured plan for keeping your data safe from vanishing or losing it by backing up and restoring it.

5. Optimize Applications and Infrastructure

To further reduce costs, improve performance, and increase any action’s efficiency, optimize your applications and infrastructure.

• Check which applications need updating to take advantage of auto-scaling and managed services.
• Ensure all your data is complete and formatted correctly so they will work better in the cloud.
• Choose and use certain automation tools to help you with smaller tasks, such as scaling and monitoring, to save more time and avoid the risk of potential errors.

6. Secure and Protect the Data

Integrate security measures to ensure compliance with industry standards. and protect your data.

• Use encryption tools to encrypt all your data and keep any unwanted users away.
• Regularly check and solve any potential vulnerabilities.
• Read all the industry regulations, such as GDPR or HIPPA, to ensure your cloud is fully compliant.

7. Move, Test, and Optimize

This is the final step, which includes moving all your verified data to the cloud, testing it, and optimizing if necessary.

• Start with smaller systems and gradually advance to the bigger ones to better spot and fix any issues.
• Don’t rush the moving process, test and double-check everything to make sure it works as expected.
• Once everything is moved to the cloud, continuously check if things are running smoothly, find ways to improve, reduce costs, and keep everything secure.

Cloud Migration Challenges to Overcome

Nobody said that this process of migrating from on-premise to the cloud is an easy and risk-free action. This comes with a lot of challenges and potential risks, such as wasted costs, complex infrastructure, data loss, downtime, and many other things that can make it difficult to migrate to the cloud. 

If you want to establish a secure transfer of the apps and data, follow the recommendations listed below:

• Optimize the cloud costs to prevent wasted costs

To prevent overspending and ensure you keep track of all your payments, use a cost management strategy to better control and monitor your cloud expenses.

• Assess your IT infrastructure to make it “fit” for the cloud

Check all of your applications, data, and hardware to ensure they are compatible with the cloud to ensure better performance and scalability.

• Resolve security issues to prevent threads

Prevent any potential security breaches by implementing security measures such as encrypting your data, setting up proper access controls, and regularly conducting security audits.

• Fix downtime issues 

Plan and test migration phases to reduce disruptions and ensure a smooth transition. Cloud migration strategy seems to be a hard process, though, with the proper preparations, you will definitely succeed and get rewarded. Adopting cloud solutions will empower you with scalability, cost-effectiveness, and market-driven innovations. Do not hesitate to take a risk today so that you won’t regret it tomorrow.

Cloud Migration Best Practices

Besides the step-by-step framework we talked about earlier, there are a few things that many people disconsider and skip, eventually having a bad experience during or after the migration process. To ensure you will have a smooth and successful cloud migration, follow these 6 best practices you have to know and apply:

1. Planning and Strategy Development

• Analyze your IT infrastructure: Start by analyzing all of your current hardware, software, network configurations, and data storage.
• Categorize your data: Thoughtfully categorize your data based on importance and complexity and decide on the order of migration.
• Choose a suitable cloud service: Use the best cloud service based on your needs.

2. Cleansing and Transformation Data

• Remove redundant data: Before migrating, eliminate any data that is unnecessary, outdated, or duplicated. 
• Standardize data formats for compatibility: Check if your data is in the same format and structure as the cloud platform; otherwise, perform necessary data transformations.

3. Ensuring Data Security and Compliance

• Implement security measures:  Use encryption and access controls to protect data both in transit and at rest.
• Ensure cloud service compliance: Check if your chosen cloud provider complies with relevant data protection and privacy regulations (GDPR, HIPAA, etc.).

4. Evaluate Network and Bandwidth

• Assess network capacity: Determine if your network’s capacity (bandwidth, latency, and reliability) will support cloud workloads.
• Implement redundancy and failover mechanisms: To ensure constant availability during and after migration, and to minimize downtime, use multiple internet service providers or load balancers.

5. Set-up Backup and Recovery

• Data backup: Create backups of your data before migration to prevent any data loss in case of critical failures.
• Develop a recovery plan: Think of a recovery plan that will help you in the worst-case scenario.

6. Testing and Validation

• Conduct testing of migrated applications and data: Before fully deployment, perform rigorous testing to identify and fix immediate issues.
• Validate data integrity:  Use validation tools to verify and validate your data integrity.

These practices will help you minimize risks and overcome any challenges that may appear during the process. Keep in mind that this is not only available during the migration process, this is an ongoing effort that goes way further than the actual migration to the cloud. Constantly manage and optimize your data to ensure everything runs smoothly, remains secure, and is cost-effective.

Real-world Examples of Successful On-premise to Cloud Migrations

A recent study states that 30-40% of companies notice a reduction in IT costs after migrating to the cloud, 50% of companies saw a 20-30% improvement in operational efficiency, and 60% of businesses experienced significant improvements in scalability and flexibility. This is all thanks to the elimination of capital expenses, better resource management, and the ability to easily scale resources up and down based on demand. Here are some names you surely heard of that took the leap and moved to the cloud:

• INSTAGRAM

Considering the rapidly growing user base that Instagram had to handle, the smartest move they could make was migrating to the cloud. It didn’t only help them become more flexible and scale further, but also efficiently add new updates and features.
