IBM Cloud is a versatile platform offering various cloud service models such as PaaS, IaaS, and containers as a service, enabling development and hosting of diverse applications including web, mobile, and IoT. It incorporates open-source technologies like Cloud Foundry and Kubernetes for deploying and managing applications in containers, providing flexibility and scalability. The document also outlines the infrastructure available for app deployment and emphasizes the choice users have in building their applications.

More openness and choice
IBM Cloud is open. You choose how you build, deploy and
manage your apps. IBM Cloud makes the infrastructure available
for you.
Compute
Choose the level of
infrastructure abstraction
based on your app’s
architectural needs.
You can deploy on
Baremetal servers, VMs,
using Docker As A Service,
or on direct runtimes.

IBM Cloud embraces Cloud Foundry
Cloud Foundry is an open source Platform as a Service – IBM
Cloud extends it with IBM, third party, and community built
services.
Deploy an app with push: cf push my_app
Bind your app to services from the Catalog:
cf create-service mysql free my_db
cf bind-service my_app my_db

1. Cloud controller sends request to BBS.
2. BBS asks Auctioneer to request auction.
3. Reps accept auction requests.
4. Rep creates Garden container
to execute task.
5. Tasks registered with GoRouter
for external access.

Containerized Applications

IBM Cloud now supports the deployment and scaling of applications using
Containers technology – your application code runs within a container.

Behind the scenes, your code runs within it's own namespace
on a shared Virtual Machine.

Docker is the most commonly used container engine used today...

Application code is bundled within a Docker Image.

The image is then used to create containers running your application.

Container?

1. Developer bundles artifacts into
a Docker image with
docker build
2. Image can be pushed to registry
with docker push
3. The image (and many more) can
be downloaded with
docker pull <image>
4. The image is used to create a
container with
docker run

Containers on IBM Cloud - Kubernetes
Kubernetes is an open-source system for automating deployment, scaling,
and management of containerized applications as clusters.

Can run Docker containers.

Containers organised into Pods.

Pods are distributed among nodes that
form the cluster.

Applications running within a pod's
containers are exposed as services.

Built-in load balancing across pods.

Supports, versioning, monitoring,
and scaling. Source: https://kubernetes.io/docs/concepts/architecture/cloud-controller/

1. User request to create a
deployment received by
kube-apiserver.
2. Desired state written to etcd.
3. kube-scheduler will schedule
desired pods on worker nodes.
4. etcd updated to reflect current
state.
5. Controller-manager, watching etcd,
will ensure current state matches
desired state.
6. Controller-manager will initiate any
required actions when
resource-change requested.
