Understanding On-Premises And Cloud Infrastructure

On-Premises Infrastructure

The term “on-premises infrastructure” describes the conventional hosting method. The hardware, data, and applications of the company are housed within its buildings. Physical servers, storage devices, and networking equipment must be purchased by the business in order to complete the setup. Power supplies, cooling systems, and security protocols need to be managed as well.

One of the main drawbacks of on-premises infrastructure is its high cost. It will take a lot of effort to reduce the amount of self-maintenance and self-protection that you must do.

Cloud Infrastructure: What Is It?

Cloud computing resources and services are referred to as cloud infrastructure. These can be obtained through an online cloud service provider. When you need it, they provide you with storage, networking, and power. There are several types of cloud infrastructures: multi-cloud, hybrid, private, and public.

Multiple users can access the resources of public clouds like AWS, Microsoft Azure, or Google Cloud. For what you consume, you pay.

You have more control and private clouds are exclusively for you. With hybrid clouds, you can use resources in diverse ways while maintaining the security of your personal data. Utilizing several cloud service providers concurrently allows you to diversify your reliance from a single business.

Types of Cloud Migration

The process of transferring data, apps, or other business components to a cloud computing environment is referred to as cloud migration. There are various kinds of cloud migration that a company could think about:

  • Lift and Shift (Rehosting):

This entails transferring data and apps from an on-premises data center to the cloud without causing any changes. Since it requires fewer changes to the apps, it’s frequently the fastest approach.

  • Switching platforms:

This kind of migration entails tweaking apps here and there to make them more cloud-friendly without altering the application’s fundamental architecture. Utilizing cloud-native capabilities to boost efficiency and cut expenses can be part of it.

  • Refactoring / Rearchitecting:

This is a more involved method that requires a lot of adjustments to the application design in order to properly utilize cloud-native features and technologies. This kind of migration is selected for mission-critical applications that demand the increased performance, scalability, or agility that cloud-native capabilities provide.

  • Repurchasing:

Swapping products frequently entails switching from a conventional on-premise license to a cloud-based subscription (for as switching from an on-premise CRM to Salesforce.com).

  • Retire:

locating IT assets that can be disabled during migration since they are no longer needed. Costs are reduced and operations are streamlined as a result.

  • Retain:

Certain components may occasionally need to stay in a private cloud or an on-premises data center due to legal obligations or other reasons. This choice frequently entails keeping portions of the IT infrastructure that aren’t ready or appropriate to move to the cloud just yet.

Every kind of migration has advantages, disadvantages, and factors to take into account. The organization’s business objectives, legal obligations, financial limits, and unique needs all influence the migration plan that is chosen.

Steps for Migrating Databases to the Cloud

Database migration to the cloud is a crucial operation that must be carefully planned and carried out to guarantee data security, performance, and integrity. The general procedures for moving databases to the cloud are as follows:

  • Assessment and Planning:

Evaluate your current database environments, including the size, complexity, and specific requirements such as performance, security, and compliance.

Choose the right cloud provider and service model (IaaS, PaaS, SaaS) that best fit your needs.

Plan for the migration process, including timelines, resources, and risk management strategies.

  • Choosing the Migration Strategy:

Decide on the migration strategy that suits your business needs (e.g., lift and shift, refactor, replatform).

Consider using tools provided by cloud providers for assessment and migration, which can automate some of the processes.

  • Database Schema Conversion (if necessary):

Convert the database schema to be compatible with the target cloud database system, if different from the source. This may involve data type changes, index restructuring, and query optimization.

  • Data Migration:

Migrate the actual data, which can be done incrementally (to minimize downtime) or in a single move.

Use data migration tools that can handle the transfer securely and efficiently. Ensure data integrity checks are in place to validate the migrated data.

  • Testing:

Perform thorough testing in the cloud environment to ensure everything operates as expected. This includes functional testing, performance testing, and security testing.

Validate the data integrity and the performance of the database queries.

  • Optimization and Tuning:

Optimize the database for the cloud environment. This might include tuning configurations for better performance, cost efficiency, or scalability.

Monitor the database performance and adjust resources as necessary.

  • Cut-over and Go-Live:

Plan and execute the cut-over to the new system. This usually involves a final data sync and then switching the application connections to the new database.

Prepare for rollback procedures in case of any issues during the go-live.

  • Post-Migration Activities:

Monitor the system for any issues that might arise after the migration.

Optimize the environment as needed based on the actual load and performance data.

Update disaster recovery plans and backups to align with the new cloud environment.

  • Documentation and Training:

Document the new environment and any changes made during the migration process.

Provide training to relevant teams to ensure they are equipped to manage, maintain, and use the new cloud database system effectively.

Each step should be accompanied by detailed documentation and should be aligned with the overall IT strategy to ensure that the migration supports business goals and provides a return on investment.

Benefits of migrating to the cloud from on-premises

For a variety of reasons, businesses decide to move their workloads and applications from on-premises data centers to cloud infrastructure. Sometimes it stems from a general desire to utilize the infinite storage available on the cloud. In other cases, companies are trying to address particular requirements, such as helping DevOps to function in better, more adaptable environments.

Having said that, the great majority of businesses anticipate reaping the following primary benefits from their cloud migration:

  • Increase accessibility

Businesses today operate in a cloud-first environment. Furthermore, since a large portion of companies employ people in a variety of places, frequently from home or in other non-office settings, it is imperative that staff members constantly have access to vital apps and data. By utilizing public cloud resources, businesses may be sure that employees’ work will not be hindered by their location.

  • Improve performance and agility

Applications that run slowly or don’t work properly don’t have the same value as those that can run anywhere. This is less likely to occur when workloads have been moved from on-premises infrastructure to the cloud because the main CSPs have cloud data centers located all over the globe to lower latency for their clients’ operations.

Moving to the cloud also greatly simplifies the process for expanding companies to make necessary adjustments and resource additions. This covers everything from in-house apps to new SaaS solutions from CSPs or outside suppliers.

  • Leverage elasticity and scalability

Businesses frequently experience abrupt increases in their resource requirements, sometimes lasting for hours or minutes and other times for weeks or months. Because of the cloud’s elasticity and scalability, you can dynamically extend computing, memory, and storage capacities when needed and shrink them when not. This lets you handle transient surges in demand. Additionally, you can add and remove additional resources as needed to meet company needs. In terms of speed, on-premises operations cannot match this advantage.

  • Achieve cost efficiency

Because of its elasticity and scalability, the cloud can also be more cost-effective in a variety of ways. For instance, no matter what, scaling up on-premises infrastructure will always be more expensive than comparable cloud charges, and scaling down is maybe even more expensive. In the long run, more effective budgeting and spending are made possible by establishing cloud consumption as an ongoing expense of conducting business.

  • Support security and compliance

Prominent cloud service providers, particularly the “big three” of AWS, Azure, and Google Cloud, provide an abundance of cloud-native security capabilities, possibly surpassing those found on-premises. By doing this, you may be able to comply with the standards set forth by strict security laws for data workloads. You can even dedicate one or more of your clouds to certain workloads if your company decides to build multiple clouds.

On-premises to cloud migration challenges to overcome

There may be difficulties in embracing the latest cloud trends and migrating from on-premises to the cloud. You may steer clear of these pitfalls with the appropriate partners and cautious planning:

  • Cost overruns: 

Bandwidth requirements, resource allocation, migration-related costs and TCO, and continuous post-migration charges can soon mount up. It is essential to arrange everything carefully in advance.

  • Databases:

It’s not always the case that moving app workloads to the cloud speeds up the migration of on-premises databases, though. The IT staff and your cloud vendor representative can work together to identify solutions to minimize any downtime brought on by moving from on-premises to the cloud.

  • Legacy infrastructure and apps:

A few legacy systems date back to the time before cloud computing. Most can be moved, but planning ahead is essential. Determine whether legacy resources need to be replaced, replatformed, or refactored prior to migration during the planning phase.

  • Security:

Security for cloud infrastructure is provided by CSPs both before and after migration; your workloads and data are not protected. Because it safeguards both your cloud resources and any on-premises equipment you manage, implementing and maintaining a cloud FWaaS is crucial.

To sum up, moving your on-premise database to the cloud is a calculated step that will advance your company into a new era of increased productivity, scalability, and security. It’s not merely a way to update your infrastructure. MegaMinds is aware of the difficulties and complications involved with these kinds of changes.
