Cloud Computing Best Practices

hi I'm James McGuire and our topic today is cloud computing best practices in the cloud to talk about that I'm joined by Charlie Lee chief cloud officer at Capgemini hi Charlie how you doing today yeah well thank you James thank you for having you here good good I know that you are in Atlanta today correct that's right sunny Atlanta so so cloud computing I think there's a certain amount of confusion out there a lot of businesses want to get on board with public cloud but a certain businesses are so reluctant to give up at in-house data center they want that private virtualized cloud the curstyn is the hybrid cloud Rijn what do you tell clients in terms of balancing public and private cloud yeah that's a great question we have a term in the public cloud for those folks who still love to have their own data centers they're called server hunters you know it really isn't a magic formula to say that you know your enterprise you have 20% you know public cloud 80% private or vice versa I really really think your thing about is certain criteria that makes private of public cloud a viable solution for your enterprise for example if you have data sovereignty needs dot a movie to the private cloud it's very specific classified security needs US government or French government you may want to consider a private cloud you may not be allowed to be in the public cloud in the distance there's certain regulatory and compliance concerns that the public cloud may not be able to address today even though they're really adding more and more compliance requirements but some are still not available you may want to consider private cloud there may be performance reasons for certain specific workloads like sa P if you want a very specific set of performance standards and SLA s which the private of the public cloud providers don't provide where there are certain limitations for example most public cloud providers today only support s DP up to 3 terabytes if you have a larger installation you probably want to consider private installation or private cloud version of s ap there are also other reasons such as I met a customer just recently that said all their applications are so fine-tune their data centers are already co-located they're all fully integrated and the cost 2d couple of them move them to the cloud and then reintegrate them all together it destroys the business case right there's still quite a bit of reasons why you want to go private but the notion certainly is true that you know if you're not in the business of running a data center you probably should let experts handle it right I mean it seems like we're we're very much living in a multi cloud world which a lot of businesses have more than one cloud contract going on at a time perhaps they're doing they have an infrastructure as a service contract with someone but they might have a data they might be doing their database needs or someone else I mean do you see that sort of a broken up you know piecemeal arrangement or not so much you know absolutely I think first of all we believe hybrid cloud is the way to go and in customers are increasingly moving to that strategy the first generation of folks that when public cloud I think was very much of a one vendor strategy they went with AWS or all Microsoft right slowly changing now we're seeing a lot of clients looking at different versions of cloud for their different needs and we also see public cloud vendors starting to distinguish themselves because the infrastructure game is almost over so they're now adding innovation is and services on top of the infrastructure that really distinguished or differentiates them from each of each other so got to see clients looking at very specific cloud providers even niche ones for specific purposes I mentioned earlier about sa P there are vendors that specialize on performance increase improving the performance of SA P in a private cloud environment there are cloud providers are very good at machine learning so really it's at a point where clients are starting to have a multi vendor strategy and using different cloud for different purposes you know as companies think about selecting a cloud a cloud provider what sort of advice do you give them in terms of kicking the tires out there because I think part of the problem is a lot of cloud vendors are not offering an apple samples comparison so shopping can be really tough I mean would it would each L folks about that absolutely there I think there's a lot of things you need to consider when you consider the criteria for selecting the right vendor what is your existing assets right if you have a time and ton of Microsoft assets today they're probably a lot of advantages of going straight to to Azure Microsoft made provides and incentives for you to do so so that's certainly something that you want to consider in other cases there are very specific mean that you have around storage data the speed of data the speed of you know creating a data lake or doing analytics and you may want to consider you know another vendor who's more suited for that some cases customers are looking only for dev and test I just want Devin said I want to drive only pure infrastructure cost and again you may want to consider you know a larger volume player for that type of workload so really there are a lot of different things to consider you also have to consider as I mentioned earlier the integration cost but you may want may have to incur you also have to think a little bit about vendor lock-in you know are you going to plan on using every single tool that particular vendor provide or are you thinking about having some portability right you know a lot of customers are thinking about being able to switch from one cloud to another based on pricing conditions in the future so if they have that strategy then obviously the criteria of selecting a vendor would be very different I think sometimes the idea of avoiding vendor lock-in or that the cloud would enable you to avoid vendor lock-in is maybe a bit of a myth of that once you get set up with a certain cloud provider within a certain way it's going to be pretty hard to switch agree or disagree on that well not necessarily so I don't see that the whole event of cloud computing or public cloud providers has changed the way we will get vendor lock-in you are as a vendor logged into Oracle or IBM as you are now to a cloud provider that really hasn't changed I think it's a strategy that you have to think about vendor lock-in is not necessarily a bad thing if everything on your business runs on Microsoft and you want to go to a juror and use service fabric and so on and so forth and you have to get all the advantages great but if you your strategy is is a multi vendor strategy you have you want to use best-of-breed solutions and you want to have the ability to be portable down the line then obviously you know you want you want to set up those strategies to not lock yourself in but I don't think a particular vendor a particular you know paradigm really changes the way you look at vendor lock-in or not that makes one it does what about the question of cloud manage and specifically the piece about costs I mean I think there's there was originally some confusion like oh we're going to save money going to the cloud but I think that sort of changed over time it's actually a competitive edge it might not be a muddy saving edge money-saving idea what do you tell folks about you know cloud management and cost some particular games I'm glad you brought that question on because we get a lot of questions today we have a lot of clients who are saying that hey we just great we've got our cost savings it's also innovative we're able to innovate so much more then we have other clients saying that hey you know what we didn't save the single dollar it's actually more expensive than before it really comes down to a few things first I think there's really poor governance policies around using public cloud I think most companies have much stricter policies internally before or or incoming in cases where companies that did not have good internal policies those still translates to when they migrate to the cloud what that means is if you're comparing apples to apples one minute of server time on a public cloud provider versus one minute server time on your own Prem yours will always be cheaper minute by minute the efficiencies that where you save money is when you save on to the scale the efficiencies and the multi-tenancy aspect of public cloud and unfortunately if you don't have a policy that says when you ramp up a server you're all going to use it for two hours and after that you're supposed to shut it down and it doesn't shut down it keeps running and running and running of course your cost will end up being more than if you have to run that server on your own premises so I think governance policy is extremely important the second is having really from loading that cloud strategy don't look at cloud as a one-time I'm going to migrate some of my applications and I'm done you really have to look at it holistically what do I do with sass what do I do with platform as-a-service comment on the leverage cloud native development down the line how am I going to integrate all my applications both on the cloud and on friend and then look at the cost holistically to see what your your overall journey will look like in the next three to five years rather than hey in the next six months if T applications then hopefully gives on infrastructure coffee gap I mean I think the the picture gets even even more complicated when you think about you know moving to the cloud for the sick of certain tools like certain vendors a fantastic edge in data analytics for example so you're you're with them and you get that data analytics in a tool but you couldn't build that in-house so maybe more expensive but then again you get access to a competitive tool that you wouldn't have otherwise yeah absolutely I mean machine learning is certainly a huge area today and in you know call two or three vendors are actually providing very very you know professional level enterprise level machine learning capabilities and it's to the point where you don't need a data scientist to actually dabble in machine learning there are a lot of tools out there for the public cloud providers where you can get started as a developer with very little data science knowledge and be able to make an impact in your in your applications and of course the machine learning piece leads us to Internet of Things because I think there's a sense that Internet of Things the competition for the IOT market is going to change the cloud market in that it's kind of a jump ball I mean no one none of the leading cloud providers necessarily have a huge advantage of IOT because that processing is happens at the edge not necessarily at the home you know Cloud Data Center what do you see about IOT and cloud Harlow's do going to interface with each other yeah I think everyone's struggling to figure out how to really monetize IOT right I think a lot of companies that figure out how to actually take the data from the devices store them cheaply or aggregate the data in a certain way or putting them in a data Lake I think the the future is really to leverage machine learning to really make sense of all that data you collected I think all the technologies and machine learning will help us decide what to do with the data in a better way and help make decisions that a human would not have been able to to garner from the large volumes of unrelated data or seemingly unrelated to us and that machine will be able to decipher that data in a better way and help us make better decisions so I think in the future you know IOT in itself is not as interesting as decisions that can be vendored by machine learning through all the data aggregation what about the future of cloud if you put on your crystal ball you look in your crystal ball for a second what do you think we're going to be talking about in cloud for the next say 2 3 5 years and whereas cloud headed and how can businesses be ready for where it's where it's going right now sure I think there are a few things that I think it is here to stay right for those people who still think cloud is that it is a niche that's already over or not I think Garner predicted a trillion dollars of IT spending the next five years which is a you know we're already not convinced it's here to stay right you think the notion of enterprise cloud is probably dead because the notion of enterprise cloud was created by some of the traditional vendors to say that these new public cloud or born and call vendors are a niche they're going to go away they're not Enterprise ready but I think that the big three you know Google AWS and Microsoft one improving that the other cloud is not just this cheap public cloud they're all Enterprise ready right no they're not Enterprise ready that's probably gone I think no office is huge in the future I think getting to a point where data centers are so automated I mean if you ever get a chance to visit some of the data centers that are run by these big public cloud providers the level of automation is ridiculous right the amount of people required to manage the operations versus any typical client data center is uncompetitive long we're talking about ten hundred thousand X difference in the amount of effort so automate that they take a huge centerpiece there the whole notion of containers I think will continue to be big which leads me to the prediction that you know infrastructure game is over right that competition that cost will continue to go down you know the players that can play in that space race to the bottom as they call it exactly the the next phase of a real competition is really enterprise apps how do you better serve apps how do you you know embrace the server less architecture of applications how do you actually run applications in a more efficient way how do you release applications faster how do you be able to support multitude versions of platform as a service and support the the kind of the portability of the applications from cloud to cloud I think it's applications game now moving moving forward and in no longer interest trevean Charlie I think you said a lot of good stuff is there anything else you want to add before we wrap things up Siddhant now James are always a pleasure to be talking with you and you know we look forward to working together again and we think cloud is an immense opportunity for companies and if they're not already looking into it and creating a holistic strategy they really need you or they're going to be left behind great thanks so much for sharing your expertise with us today all right thank you Dave all right
