Containers are a hot ticket in 2016, and everyone seems to want to throw around the Cloud Native Application buzzword in relation to them. But despite a common perception, those two technologies are not joined at the hip! In this talk we'll distinctly cover what makes an application Cloud Native and talk about building applications with containers.

Notas del editor
- There are new applications but there are also old applications that could be operated in new ways Getting agility includes thinking about new strategies for operating applications Micro-services and automation are a target for everyone Incremental approaches to getting there Leveraging open source infrastructure for these cases Flexibility and Freedom Innovation Integration Containers are not cloud native, but are independent and even complimentary to cloud-native Talk about this to help move towards a strategy to embrace containers
- Our bottom up approach to supporting applications doesn’t work moving forwards What are you hearing more about nowadays? Containers and makes sense since it’s a new way of operating things Less reliance on virtualization layers for availability Efficiency of hypervisor isn’t driving more workloads and use cases People are interested less in clouds Talking to developers in your org about infra and cloud goes nowhere Workloads have been tested in clouds, and some have moved that way Recognized that predictable workloads can be better served in private clouds Back to private cloud virtualization layers or IaaS? Has to be a new layer of abstraction above the infra but mindful of infra For customers that haven’t gotten to cloud yet, see an opportunity to enable portability to get there and back Innovation is happening at higher layers, top down approaches for the applications versus bottom up
- Real tangible benefits to operating old and new stuff in new ways New applications can’t be operated as monolithic applications Types of applications Could be monolithic or new micro-service based scale-out applications Could be custom, OSS projects, or even purchased applications
- Choices and opportunities Support developers of apps in better ways Old and new applications in better ways Integrating platform and lifecycle capabilities to the applications Micro-service focused platforms that help operate applications
- What is platform 2 and platform 3? Need to take a serious look at containers and cloud native applications Think about about the platform is supporting Are applications in containers considered platform 3? Can cloud native applications be platform 2?
- We are seeing three general types of application platforms emerge Custom container platforms have been the most popular for early adopters Here any combination of platform components have been used Take anything off the shelf and “roll your own” Enables ultimate flexibility Container platforms tend to be where the attention is in the Enterprise Supported as a pre-defined stack Some parts can be replaced Cloud-native platform is completely packaged and moves forward as major releases
- Most important thing is that we must consider operating in new ways Must support the agility of new applications Open source infrastructure Flexibility and freedom Integration innovation
- Here we flip the model upside down Integration taking place through code taking advantage of open source Infrastructure operated as software then is consumed by applications and consumes dependent layers of infrastructure Application platform handles infrastructure
- Enabling infrastructure as code is key Cloud native platforms like Cloud Foundry Container platforms like Docker, Mesosphere, and Kubernetes Containers can be used for both and are key to delivering a layer that promotes portability and abstraction from infrastructure
- Deliver a necessary abstraction to the operating system for delivering applications
- Whether it’s a container or cloud-native platform they are both driving at similar goals Tend to enable said things Tend to differ in their requirements on the applications
- Cloud native platforms Tend to be more strict If you meet certain requirements the applications are compatible and can be operated in new ways Applications in containers Containers can work with any application Tend to be complmentary to
- Option 1 Re-write your application to be 12 factor Split front end, middleware, backend Backend data services get sent to shared service But what operates the shared service?? Option 2 Leverage containers Move them into containers, or rewrite Leverage a container platform for operating Option 3 - Build your cloud native application and then lerverage container platform to house the data services
- Rationalizing your applications is important Cloud native is fine for applications on top Doesn’t work for applications on bottom
- So we we end up with an application that spans both
- So we we end up with an application that spans both
- We are EMCII so let’s drill further into data services in containers
- The data for your applications needs to live somewhere. Wouldn’t it be ideal if the management of your micro-service application was done by the same platform?
- Managing the persistence of your micro-service application would look like this. In platform 2 Virtual machine infrastructure would provide availability to my monolithic application Moving towards platform 3 Lifecycle is handled by platform with the application Availability enabled through the container platform Scale-out applications work here to provide availability themselves
- This what a persistent application in a container separate from a cloud-native or micro-service application really looks like.
