Hybrid Cloud Explained



hi everyone my name is sai venom and I'm a developer advocate with IBM today I want to talk about hybrid cloud if you're watching this video then you're probably tasked with a very important role of figuring out how hybrid cloud fits in with your company's architecture or maybe you're just a little bit curious about this cloud computing approach either way essentially hybrid cloud boils down into a mixture of a private as well as a public environment and essentially the two are working in tandem to run your workloads and applications to better explain hybrid cloud I want to start with an example let's say we've got a fictional company Acme freight who is essentially tasked with you know running shipments Acme freight has an existing on-premise application an ERP application which many people might be familiar with is an enterprise resource planning app which enables them to manage their shipments and make sure that they make it there on time but let's say that this ERP application is made up of three major sections we've got the BFF in the middle here we've got the chunk of the ERP application that kind of runs things like in inventory truck drivers deliveries shipments that kind of thing and we've got the at the bottom here a user registry human resources that kind of thing so the BFF is going to basically handle any time front-end requests are made to make sure that web dashboard looks great but Acme Freight has just created a new mobile application that needs a new BFF application to actually serve those endpoints so to do that the team decided to create a new BFF layer on the public side so they've started with a new public cloud and they've decided to deploy the back-end for this mobile application on this cloud so we've got the mobile bf application here so the main thing to keep in mind here so only the mobile BFF application is running in the public cloud so they still need a way for this to interact with the existing ERP app to do so they'll simply open up a tunnel that allows the mobile BFF application to work with those private endpoints that the ERP application serves so that's one of the key tenants of a hybrid cloud environment is the fact that they must be interoperable essentially meaning that the public components and the private components are working in tandem so so far the truck delivery drivers are loving this new infrastructure they're able to use their mobile apps to kind of submit whenever a delivery is made but what they've noticed is during the holiday season or peak hours this whole system is bogging down and is leading to delivered deliveries that are late and shipments that are being missed to tackle this Acme Freight decides you know what it's about time we need to start breaking this model like monolith down so they decide to move the ERP portion the big chunk break it apart into micro services and move it to a public cloud to do so they take advantage of Linux container technologies things like docker as well as container orchestration management tools like kubernetes and successfully they move that ERP layer to the public cloud not an easy task so we can imagine that there's a number of micro services that represent that ERP application that are running in a public cloud and they're working with docker technology and Kupa kubernetes technology keeping everything orchestrated and scaled out that's one of the great things about taking advantage of a public cloud is that there's seemingly endless public resources to to scale out your application so although they get to keep their existing on-premise or ERP architecture they start moving to the public cloud and take advantage of the scalability and the capabilities that are offered there another advantage of working with the public cloud you're no longer locked into a specific vendor traditionally with monolithic applications maybe you're working with a Java EE stack you're you're kind of forced to use the capabilities that the stack allows you to use but with public cloud you can kind of go window-shopping there's lots of open source projects out there programming languages that you can use and with micro-services speaking on public interfaces you know all of those services can talk to one another regardless of the technology that they're written in so definitely by taking advantage of the public cloud they get to use cool third-party services so Acme Freight decides you know we can do better with delivery rerouting whenever there is a snowstorm or inclement weather and so to do that they hook up this ERP application to Watson and take advantage of some of the cognitive capabilities to power delivery rerouting so effectively where there were taken advantage of the portability features offered by taking on a hybrid cloud architecture the last thing I want to touch on is security although Acme Freid moved over the mobile BFF piece as well as the ERP application and to micro services and you know in a perfect world maybe they've even phased out these two portions they continue to keep the user registry on Prem because that's something that they want to keep firewall they want to keep it completely secure and always on their own infrastructure and hardware that's one of the great advantages of hybrid cloud is that they can continue to keep certain resources firewalled and on Prem while taking advantage of the public cloud to continue to run their applications and workloads so together hybrid clouds you get the features of interoperability scalability portability as well as security all of these come together to enable developers and companies to take advantage of the best of both worlds when running their applications if you want to learn more about hybrid cloud check out the
