Multi cloud mode is not a "master key"

Not every enterprise needs to be cloudy , But those enterprises that need to be cloudy need to consider three things .

In an uncertain economic environment , How to adapt to environmental changes faster is one of the necessary skills for enterprises to survive and develop . Under the global digital tide , Cloud services have become a big help to enterprises . The multi cloud strategy has gradually become the consensus of cloud services . however , It should be noted that , Although the interest of many enterprises and institutions in the multi cloud model continues to rise , But building a truly cloud spanning infrastructure is complex and expensive , And the multi cloud model is managing 、 The challenges brought by operation and maintenance can not be ignored .

Cloud cost management company Yotascale Of CEO And founder Asim Razzaq openly , Not every enterprise needs to be cloudy , Choosing whether to invest in a multi cloud architecture depends on three things ： How much computing demand does the enterprise have 、 Budget and redundancy .

PART 01

Consider calculations and calculate costs

As PayPal Former engineering director of the internal platform ,Razzaq I have been thinking about IT Cost of infrastructure 、 Performance and scalability , And gradually realize that no matter where the application is running , Don't stick to a single strategy .

Razzaq say ：“ Gu Geyun has done better in analysis and machine learning ,Azure and AWS Better coverage and core infrastructure . If you are a Microsoft store user ,Azure Is the best choice .”  There is no one size fits all solution , Everything is a trade-off .

Canalys Cloud Research Analyst Blake Murray Agreed ,AWS,Google and Microsoft And other modern super large-scale cloud manufacturers have built solutions that support multi Cloud Architecture , In essence, it is more closely connected with competitors .“ Overall speaking , Technology is becoming more and more integrated , Customers also began to take advantage of the power brought by the connectivity ecosystem . Large scale enterprises see the value of connectivity , And is trying to create more competitive solutions .”

Razzaq mention , To deploy a multi cloud strategy , Architecture must focus on . If you are considering cloudy , The existing architecture is not ready for the abstract requirements of containers and microservices , So it is very difficult to migrate to a cloudy environment .

Razzaq Also said , Enterprises should not hesitate to put some data or applications into another cloud for testing . Because doing so can put pressure on the current service , It will help to obtain greater discounts in the final cooperation .

“ Handing some of the workload over to another vendor can give you more advantages in negotiations . It means ,‘ We have other options , So you'd better give us a more attractive discount ’.”Razzaq say .

Murray Pointed out that , Although providing multi cloud support is part of every cloud vendor's business , But only when the business scale is large 、 And the performance time is long , Multi cloud selection will have an impact on the result of discount negotiation .

Murray Tell us , Moving data from one cloud to another can also be very expensive . He also pointed out that , You can also talk about good discount results by cooperating with only one cloud manufacturer .

PART 02

The necessity of redundancy

Some services are necessary for business operations , Some services are not .Razzaq Express , He was in PayPal when , Core services such as login and payment processing must have failover functionality , However, less important systems such as coupons and analysis and investigation may not be able to obtain this level of operation guarantee . He said :“ The practical approach is to establish redundancy for critical services .”

Razzaq say , If the selected cloud manufacturer is only in another place in the same city , Or there is a data center in another area of the same power grid , It's not enough. .

“ A lot of times , The failure will produce a chain reaction , A service goes down , Another dependent service is also down , And cause more trouble . So you need to build redundancy in a cloud environment that is independent and in different regions .”

Murray said , Relying on multiple independent suppliers may not be the right way to solve the redundancy problem .

He thinks that , Although cloudy has many advantages , But cloudy environments often add complexity . And cloud vendors are good at providing redundancy support , So don't worry too much .

PART 03

Should we avoid cloudy ?

Gartner Express , Many companies choose a multi cloud strategy for the same reasons Razzaq The judgments are basically the same ： This includes improving agility 、 Modular architecture and cost optimization . On the issue of which kind of enterprises should avoid cloudy, the two sides are also quite consistent .

Both parties agree , The investment in a single platform can enhance the understanding and grasp of the expertise of a specific technology stack .Razzaq Express , This is an ideal choice for retail companies and other enterprises focusing on a single business . Therefore, this kind of enterprise is not suitable to choose cloud .

Murray Think , Whether to choose a multi Cloud Architecture or not , It has nothing to do with the industry , It is related to the characteristics of the workload itself .“ A single cloud environment has a single skill set , There is no cross cloud performance risk , It can reduce the cost of cross cloud migration and reduce management complexity .”

Murray Also mentioned , In view of the compliance requirements and data sovereignty requirements of industries such as banking and healthcare , It is also best to avoid adopting a multi cloud strategy .

that , Whether the multi cloud strategy is suitable for your enterprise ？ This requires careful consideration of many factors . in the final analysis , If you are still in doubt about the need to use multicloud , It's better to stick to a single cloud vendor , Plan before you act .
