Trove - Database as a Service

• Database as a Service - Automating complex database administrative tasks – Deployment, Configuration, Scaling, HA

• Single Admin Tenant Database per Nova instance

• Datastore type - Relational and Non-Relational

• Pluggable – Support for MySQL, PostgreSQL, NoSQL – Cassandra, MongoDB, Couchbase, Redis

• Integration with other projects –Designate, Heat, Neutron

Trove API Functionality

Management Create/Delete/Show/List Database

instance, Database, Users, Flavors

Security Support for Security Groups, No SSH by

default

Configuration

groups

Support for user defined configuration

settings (MySQL, MongoDB) – Eg:

max_connections, Buffer pool size etc

Backups Support for full backups and incremental

backups using Swift (MySQL,

Cassandara, Couchbase)

Replication Async mysql master-slave replication from

snapshot of master

Clustering Support for shards - three member replica-

sets (MongoDB)

Sahara – Data Processing as a Service

• Cluster provisioning - Create and Manage Hadoop clusters

• Node Group Templates – Defines instances/nodes within a cluster that will each run selected hadoop processes and store data

• Plugins – Responsible for provisioning Hadoop cluster – Vanilla, Hortonworks, MapR, Clouder, Spark

• Cluster Templates – What Node Groups to be included and how many instances to be created in each

• Anti Affinity Groups – Processes may not be launched more than once on a single host

• Cluster – Represents a Hadoop cluster run using Cluster Template

• Image Registry – Used to provide additional information about images using tags

• Cluster Scaling - Change instances in a existing Node group or add new Node groups

Sahara

• Configure HDFS and MapReduce parameters at Node and Cluster level

• Integration with Cinder, Swift, Neutron, Heat

API Functionality

Data

Sources

Stores URL which designates

the location of input and

output data

Job

Binaries

URL to script or Jar file stored

in internal DB or Swift

Jobs Specifies the job and lists all

individual Job Binary objects

required for execution

Job

Execution

Monitor and Manage a Job

executed/launched on a

Cluster

Ironic – Bare-Metal as a Service

Ironic

• Service for Bare metal management

• Ironic API – RESTful API service

• Ironic Conductor – Interacts with hardware; asynchronous handling of both requested and periodic actions

• Ironic Python Agent – utility service temporarily booted on machines to provide remote access to hardware for provisioning and management

• Ironic Drivers – Communicate with hardware devices

• Nova driver

• Using Nova API can provision bare metal servers

• Based on Open technologies

• DHCP, TFTP, PXE - In a PXE environment, TFTP is used to download NBP over the network using information from the DHCP server.

• Ironic API – Chassis, Drivers, Links, Nodes, Ports

Magnum – Container as a Service

• Nova Container virtualization drivers - Docker, LXC, OpenVZ, ZeroVM

• Heat resource for Docker

• Container as a Service (“Nova of containers”) - Provide a REST API for Container management

• Provide app isolation, portability, manageability with containers

• Containers in VMs, Bare Metal, Containers

• Resources

• Container – a container

• Node – a bare metal or virtual machine where work executes

• Bay – Collection of nodes where work is scheduled

• Service – a port to Pod mapping

• Pod – a collection of containers running on one physical or virtual machine

Kolla – Containerization of OpenStack Services

• Containerization of OpenStack services - All "core" OpenStack services implemented as micro-services in Docker containers.

• Technology

• Dockers – Deploying containers and managing images

• Ansible – Orchestration tool for multi node deployment

• Jinja2 – Templating language for Python

• Developing and Deploying OpenStack service using Kolla

• Supports deployment from binary and source across multiple distributions - CentOS, Debian, Fedora, Oracle Linux, RHEL, and Ubuntu

• AIO and multinode deployment using Ansible with n-way active high availability.

• Development environments using Heat, Vagrant, or bare-metal.
