Cloud Storage Solutions For Business: Now With Tiered Storage
Data storage has no solution for one size for all fitting occasions. A cloud-based storage is developed on a well-managed plan. Companies often choose a Cloud-based solution for fulfilling the minimum requirements of data. However, a wiser approach lies in the segregation of the data based on usage of data.
The best possible solution is reached when there is an agreement on the storage requirements. With due consideration for the cost perspective as well as removal of hindrances like performance bottlenecks, the best solution is the different tier of storage devices being installed in the cloud-computing servers. The data need to be understood, with factors like how often the tier of data needs to be accessed and its place among the business activities.
The information usage and the access model used in legacy systems involved the creation of data, modification of contents with a quick ending of the productive life cycles. The data was inactive for a long period. This trend on legacy data still exists with the need for data footprint reduction techniques (DFR) like reduplication, compression, archiving, thin provisioning and storage tiers.
This inactive data, which occupies the storage space, must be replaced by the active data. The objective is the removal of inactive data from the high-performance storage media tiers like SSDs or 15K HDD, to the lower-cost, higher storage HDDs. A better resource utilization is done with the improvement of the return on investment, along with the reduction in overall storage costs.
The tiered approach will also ensure that the data does not lose its value over a certain period of time, as in the traditional data lifecycle model. The near-line or the online accessibility actually helps to increase the value of the new model. The data is created, read, copied, analyzed, downloaded and new versions are created, based on the activity model offered by the cloud-based applications, functionalities, and the services. Another important step is the recognition of the activity pattern for the alignment of the approached tier of the storage medium for the applications, operating in the private and public cloud storage.
The type and classes of services provided determine the types of tiered storage. If the cloud services need low cost and no-cost capabilities but not high performance, then the energy efficient HDDs are to be chosen.However, when faster response time (latency) or increase in the number of active users is needed, then the best fits are the SSDs. The various attributes of the technologies, as per the changing needs decide the way the alignment of the storage media is done.
The first step towards the choice of the cloud storage solution lies in the finding of the spectrum of the data or the tier of data. For this purpose, we need to find the different solution tiers and the difference in the performance levels. The successful storage strategy is met when the best storage tiers meeting the storage needs is decided.
