Introduction
Amazon Web Services do not need an introduction. AWS not only provides computing, storage, and other capabilities but also supports IT infrastructure services that are central to most digital businesses. It is beyond doubt that in order to migrate to aws, a planning strategy needs to be chalked out in the beginning. This has advantages like minimization of capital expenses and reduction of administrative costs. In addition to this, the performance gap in businesses gets filled and new features of AWS are utilized. There are a lot of strategies that can be taken into account when migrating to AWS. The aim of this paper is to look into migration strategies that can be utilized for the migration of different applications to cloud environments.
A look into a planned migration strategy
The migration strategy can be e discuss in six distinct steps. The first step is the cloud assessment phase. In this phase, three important assessments are carried out. The first assessment is technical in nature while the second assessment deals with natural aspects. The third assessment is related to security and compliance issues. After the assessment has been carried out, we need to identify different kinds of tools that can be utilized in the migration process. The next two important steps include the migration of various products and applications and the creation of an assessment strategy. This is important to get details about the migration process for continuously monitoring the progress. There are a lot of benefits that are associated with the cloud assessment phase. Such benefits include lower latency and higher flexibility. The scalability and agility that we get after the cloud assessment phase are also commendable.
The second phase is popularly known as the proof of concept phase. This is critical for getting the first insights of aws. It also helps in the construction of a pilot strategy and getting knowledge about the technology used for migration purposes. This phase is also crucial as it enables us to test the software in the cloud ecosystem.
It is in the third phase that we involve the process of data migration. It is here that we assess the different migration options available to us. The advantage that we get during this phase is automated backup management facilities.
In the fourth phase, we start the process of moving applications to the cloud. We usually adopt a hybrid migration strategy in this phase. In this phase, we also construct a cloud-aware layer that enables us to reduced redundancy and scale the storage process.
The penultimate phase of the cloud migration strategy involves the creation of a dashboard for the management of different types of resources. This phase deals with various security concerns and is used for leveraging other aws services.
The final phase is called the optimization phase which is used to improve efficiency while simultaneously monitoring the other activities during the migration process. This phase also enables us to re-engineer our applications if the need arises. The decomposition of relational databases is also a key component of this phase.
The final workstation
After the migration process has been completed, it is time to run all the applications and ensure that the migration process has been executed as planned. This is the time when one can take advantage of different types of available features and services in cloud environments. In a contingency case where a particular software is not functioning well, steps can be taken to restore it to its original state.
It is at this stage that we can use the auto-scaling option of the Amazon Web service. In addition to this, we can strengthen the security shield by restricting access to Amazon Web service resources for different kinds of users. Data privacy and protection form a critical component of this stage. We can also adopt a recovery strategy to restore the applications in case of a sudden halt. The process of upgrade also becomes easy if all the above steps are followed in a sequential manner.
Concluding remarks
The wide range of benefits that migration to Amazon Web service brings is extremely commendable given the reliability options. The range of advantages associated with Amazon Web service cloud is serving as an incentive for enterprises to take their first migration step. In the future, we may witness a race to the cloud environs as more and more companies reap the benefits from aws cloud migration.
