Within the publish, What’s Multi-Cloud?, we outlined multi-cloud within the context of the “data-gravity” ache factors multi-cloud options ought to purpose to unravel and we emphasised the distinction between multi-cloud and multiple-cloud knowledge architectures. As a reminder, in that publish we outlined data-gravity as a very painful number of cloud vendor lock-in:
Information gravity is the phenomenon the place the extra knowledge a corporation collects, the harder it turns into to maneuver that knowledge to a brand new location or system. Within the context of the cloud, as knowledge accumulates in a cloud, it attracts extra functions, providers, and customers to the identical cloud. This self-reinforcing “gravitational pull” makes it more and more difficult to make knowledge obtainable to functions and providers in different clouds. Consequently, organizations affected by knowledge gravity will discover themselves locked into a selected expertise or vendor, limiting their flexibility, agility, and skill to handle cloud vendor prices.
With the background established, we’ll flip consideration to serving to you reply the query: “Is my knowledge structure multi-cloud our a number of cloud? Probably the most vital distinction between a number of cloud and multi-cloud deployment fashions stems from whether or not the answer is architected with application-first or data-first design ideas.
A a number of cloud deployment begins with choices relating to the place to run functions, and which native and third-party cloud providers to make use of. Invariably, application-first decisioning leads to knowledge being “distributed” to the places/clouds by which functions and providers run with every knowledge set in a silo having its personal “quantity” of data-gravity.
Against this, a data-first structure begins with an evaluation of the info required to allow functions and the complete spectrum of information providers utilized by the group. With that understanding, decisioning can flip to the place to “place” and how one can handle knowledge. This decisioning ought to purpose to realize three aims:
- Maximizing the breadth of the applying and cloud providers to which knowledge could also be introduced
- Minimizing operational prices, complexity
- Offering a platform for flexibility and agility for the long run
In conventional application-centric architectures, these aims are incongruent; and to a big diploma, in specific battle given the paradigm of information following the applying. However in a multi-cloud design, these aims may be introduced into concord by putting knowledge in a area with a number of cloud suppliers in an information retailer offered by a cloud-agnostic third-party.
The pure end result of this knowledge first strategy to architecting for the cloud is critical flexibility to find out which cloud(s) by which every software may be optimally run from a value/efficiency standpoint.
Within the spirit of an image tells a thousand phrases, the diagrams under replicate the a number of cloud design that stems from application-first design ideas contrasted with the multi-cloud design from data-first design ideas.
With a purpose to higher distinguish between a number of cloud and multi-cloud design ideas, under are a number of questions price contemplating:
- Do you often transfer, copy, or synchronize knowledge between your on-premises environments and a number of public clouds or between a number of public clouds?
- Do you might have duplicate copies of some or all your knowledge saved in a number of public clouds or your on premises environments?
- Are you experiencing issue making knowledge obtainable to the functions and providers your inside knowledge shoppers are utilizing within the public cloud?
- Do your cloud vendor choice choices begin with a choice relating to which cloud to place your software in (or with the choice of a selected cloud service), quite than with a choice relating to the place to place your knowledge?
- When you consider multi-cloud methods do you first take into consideration how one can make your software moveable and later about the place your knowledge is saved?
In case your solutions to the questions above lean towards “Sure,” you’re possible counting on application-first design ideas in your cloud deployments. Coincidentally, you’re in all probability experiencing the ache factors that stem from data-gravity, together with the necessity to transfer and duplicate knowledge throughout your on premises and cloud environments.
In case your group is experiencing the ache factors related to a number of cloud design ideas, it’s possible you’ll profit from shifting to data-first design ideas which leverage true multi-cloud knowledge storage options. A real multi-cloud answer will allow your group to flee data-gravity by presenting one copy of your knowledge to functions and providers in a number of public clouds concurrently; accelerating your group’s data-driven transformation and enabling you to optimize the choice relating to the place every workload runs primarily based on application-level value/efficiency concerns.
