The migration of business-critical infrastructure, applications, and software platforms to the cloud is one of the most high-stakes projects a business can undertake. The profound ongoing impacts of cloud adoption on IT expenditures reflect the reality that cloud migration is a fundamental condition for any digital transformation.
An enterprise must have a cloud migration plan supported by solutions that limit the risks of expensive, time-consuming complexities and substandard workload performance to realize the full potential of these investments.
This post will discuss Teradata cloud migration and its multiple applications in the IT industry. Read on to discover more about migrating to Teradata’s cloud.
What is Teradata Cloud Migration?
Teradata cloud migration comprises moving workloads to the cloud from an on-premises environment such as a data center. These workloads can include an application, a group of virtual or physical servers, or even a database in an analytics ecosystem. Additionally, a migration plan can comprise transitioning from one cloud to another.
Migrating to Teradata cloud computing has unique high-level benefits for analytics workloads that aren’t available if you only use on-premises infrastructure. These workloads are transferred from settings with legacy infrastructure, which consists of expensive hardware and software to maintain. Furthermore, they cannot provide, on their own, the speed and scalability necessary for real-time and AI-powered analytics.
The complete Teradata cloud migration process typically aims towards a public cloud environment delivered and maintained by a major cloud provider like Amazon Web Services, Google Cloud, or Microsoft Azure. A multi-cloud approach is more valuable if a business uses multiple cloud computing services across more than one cloud.
In addition to the public cloud and on-premises assets, migration might also entail a hybrid cloud. This configuration protects current infrastructure and can enable greater performance and cost control while leveraging the potential of innovative public cloud services. Data analytics solutions can be transferred to a hybrid cloud environment to preserve this flexibility.
Types of Cloud Migration
Several strategies are available for migrating workloads to the Teradata cloud, varying from basic to sophisticated. The cost and effort necessary for a successful migration will depend on the usability of the solution and the different data migration management procedures. Therefore, employing a highly automated and organized multi-phase strategy is best to guarantee a seamless transition to cloud infrastructure.
Here are two primary migration strategies:
1. Rehost (also known as lift-and-shift)
A lift-and-shift migration is the simplest cloud migration strategy. It entails transferring an existing system to a cloud environment with its legacy configuration and application architecture functioning on infrastructure-as-a-service (IaaS). Rehosting may be affordable upfront, but depending on the tools employed, it may cost more than other alternatives in the long term. The increased expenses are due to the opportunity costs, high operational expenses that come with running unoptimized workloads, and the absence of optimization for cloud-native APIs and key functionalities.
2. Replatform
Replatforming, a little more complex migration than rehosting, requires small workload adjustments before moving it to the cloud. If you’re uncertain about the installation process, don’t hesitate to visit hexaware.com and obtain professional help from Teradata cloud migration specialists.
Common phases in the replatform strategy include changing the middleware and switching to a cloud provider’s platform-as-a-service (PaaS).
Replatforming can impact an application’s database interaction and scalability. Replatforming introduces infrastructure-as-code, which facilitates the configuration and supply of resources using machine-readable files.
Uses of Cloud Migration
Teradata’s cloud migration objectives are generally the same – improving performance, reducing expenses, and increasing flexibility. Some uses of cloud migration include:
1. Flexibility and scalability
On-premises workload scaling entails acquiring, deploying, maintaining, and removing or adding physical servers. This technique is complex and can quickly become costly. On the other hand, cloud computing supports scalable on-demand computing to be deployed depending on fluctuating workloads. Furthermore, elasticity supports dynamically scaling cloud resources to match rapidly changing workloads.
2. Flexibility
Public cloud migration doesn’t always entail abandoning your on-premises resources. Cloud deployment solutions are quite flexible and often include hybrid cloud systems. Therefore, an organization may get the most out of its current investments while also taking advantage of the public cloud’s endless resources. For instance, the cloud facilitates access to vital resources, such as superior ML and AI tools, which users can use to automate and streamline their workflows.
3. Better performance
Migrating from on-premises to the cloud can substantially improve performance, especially if the legacy system was old or far away from the users. In addition, the cloud provides additional features, such as auto-scaling, that provide satisfactory performance even when the demand surges. Hybrid clouds can keep local on-premise infrastructure and software running at peak performance when required.
4. Increased functionality
From artificial intelligence and machine learning to cyber security, the leading cloud service providers are at the forefront of innovation. This means cloud users can take advantage of a consistently growing number of valuable features that would be out of reach if they exclusively relied on on-premise infrastructure. Therefore, modernizing and optimizing workloads becomes much easier due to the abundance of built-in services.
