Legacy Virtualization ContainerizationYear 2014 à

What is Containerization?


Light-weight OS level sandboxing of applicationsRuns multiple isolated apps on single host without hypervisor

Currently, the hottest trend in datacenter innovationNext step for optimizing computing resources post VMs

Build and configure once, run anywhereIdeal for DevOps and modern micro-service architectures

Significant buy-in from both start-ups and large vendorsPackaged Software: MySQL, MongoDB, Redis, NodeJS…OS Vendors: Microsoft, Apple, Red Hat, SUSE, CoreOS...Clouds: Amazon, Microsoft, IBM, Rackspace, Google...Major Users: Netflix, Paypal, eBay, Google, Spotify...

Why Containers?


Containers provide a more efficient use of Resources:: Eliminates Hypervisor reducing virtualization overhead while still allowing separation and isolation of multiple tasks on one host without relying on a separate OS, saving huge amount of HW resources compared to bulky VMs which emulate physical servers complete with OS

Allows Easy Application Portability between different hosts within DCs, DC to DC/ DC to Cloud (Private, Public, Hybrid) / Cloud to Cloud

What is Kontena?


Open Source container & micro services platform built to maximize developer

happiness. Works on any cloud, easy to setup, simple to use.

How does it work?

Kontena GridA number of physical or virtual machines – Kontena Nodes– create a Kontena Grid. The nodes may be located anywhere; in single data center, different AZs or different cloud providers.

Overlay NetworkKontena will automatically create an overlay network powered by Weave and connect all nodes of a Grid. Overlay network enable services to communicate with each other in multi-host, multi-AZ environment.

Service DiscoveryKontena has a built-in service discovery powered by etcd. It is used to automatically assign DNS addresses for any services running in Kontena. It is also used by Kontena’s load balancer for zero-downtime operation.

OrchestrationKontena’s orchestrator is distributing, running and monitoring all Kontena Services in a Grid. Services may be stateless or stateful, and they are automatically distributed across Nodes in a Grid.

Containerized WorkloadsWith Kontena, all containerized workloads are described as Services. Kontena Service is composed of containers based on the same image file. Services may be scaled and linked together to create complex elastic apps.

OS

Docker

Kontena Nodes & AgentKontena Agent may be installed to

any machine capable of running Docker. It is running as a privileged

container in a machine.

Kontena MasterKontena Master is orchestrating the

entire Kontena system. It provides APIs used by Kontena CLI, Web UI and

third party integrations.

Kontena Master may be installed as high-availability setup if needed.

All Batteries Included!

Built-In Image RegistrySometimes projects can not use publicly

hosted container image registries like DockerHub. Kontena comes with built-in

container image registry providing private and secure solution.

Built-In VPN AccessAll containers are run inside a virtual private

network by default. Nothing is exposed to Internet unless explicitly defined. With

Kontena’s built-in VPN access developers can securely access those resources.

Built-In Load BalancerKontena comes with built-in load balancer.

Based on Haproxy. It features fully automatic, zero-downtime operation due to deep

integration with Kontena’s service discovery and orchestration technology.

Aggregated Stats & LogsKontena provides real-time log and statistics streams containers. The streams may be grouped and aggregated to produce service level streams. This allows easy viewing of logs and statistics for your application CPU, memory, disk and network usage.

User Management with Audit TrailAll events and actions performed through Kontena CLI or APIs are logged into audit trail. Combined with users and access control, the audit trail support makes Kontena a reliable and secure solution for any enterprise deployments.

Built-In Secrets ManagementWhen your application requires access to APIs or databases, you'll often need to use secrets such as passwords and access tokens for authenticating the access. Kontena Vault is a secure key/value storage that can be used to manage secrets in Kontena.

“Includes all the s**t you don’t want to implement by yourself”

Works on any Infrastructure


Kontena works on any public cloud or in your own private datacenter; hybrid environment, virtualized or bare metal.
