Containers will distribute your application, while giving you access to theCore of it.
What are the Containers?
During the past few years the internet infrastructure and DevOps have been changing rapidly, due to Linux containers like Docker – a whole new world of a container development toolbox. This toolbox got everyone excited!
A container is made possible by the Linux Kernel that allows lightweight partitioning of an operating system into isolated spaces (containers) where applications can safely live and just exist. The industry is so excited because containers represent the next standard in how applications are defined from development and all the way up to production. The most important benefits of containers are efficiency and speed. Containers are so much faster to provision and way lighter-weight to build versus old fashioned methods like Virtual Machine images. Containers in a single OS are also more efficient at resource utilization than running a Hypervisor.
Virtual machines include the application, the necessary binaries and libraries, and an entire guest operating system — all of which can amount to tens of GBs.
Containers include the application and all of its dependencies, but share the kernel with other containers, running as isolated processes in user space on the host operating system. Docker containers are not tied to any specific infrastructure: they run on any computer, on any infrastructure, οn any cloud.
Everyone is trying to get into containers (WSJ on the industry shift) and they become game-changers at scale. Companies like Microsoft, Google and Facebook leverage containers to make their teams more productive and to improve utilization of their resources and infrastructure. In fact, Google credited containers for eliminating the need for an entire data center – not in the near future, but now.
Containers VS VMs
We use containers almost from the beginning of Docker. Virtual Machines are too slow and too inefficient to power a top-of-the-line, Industry 4.0 application management platform, that we call the next generation of hosting or just “Application Living”.
We choose containers because of:
- Fast provisioning: Containers are provisioned via our API into an already fine tuned infrastructure. We can scale up/down or redistribute containers all over the world in seconds, not hours or days.
- Cost efficiency: Containers are scaling up super easy. So the cost of a small set of containers is so much less than even the smallest cloud instances, droplets, servers or VM. This way we can spread out across many machines without going out of budget.
- High availability: We run containers on different regions, locations, cloud providers and hardware specifications. If any of them goes down (even a whole region), we just change routing traffic from the Edge to other containers, somewhere else.
- Smooth scaling: Containers can handle application peaks like a charm. No downtime, even with millions of visits, which is near to impossible with old-fashioned centralized VM infrastructure.
- Full automation and isolation: Every application is running on many isolated containers. The platform is a giant, full-automated, share-nothing pool of individual containers that are living on their own on various locations, using machine learning and AI to take various decisions.
The Future of Containers
We keep seeing that all big internet companies have been utilizing containers for nearly a decade. But it’s still early days for containers and for what is coming ahead.
We believe that a lot of exciting stuff and practices are coming in containers, from Docker to CoreOS and RedHat’s OpenShift. We expect to see solutions using distributed containers as a primary architecture, as well as seeing new offerings from PaaS and IaaS providers helping developers ship faster.
Containers just connect billions of creative people around the world with incredible technology, and we are very excited about that.
