PA200 - Cloud Providers

Recap of Cloud Types

• More detailed in Cloud Service Deliver Models
• Datacenter Virtualization – oVirt
• IaaS – Infrastructure as a Service – OpenStack
• PaaS – Platform as a Servise - OpenShift
• SaaS – Software as a Service – Microsoft Dynamics CRM – mostly abandoned
• xPaaS – extended PaaS – integrates aPaaS (Application), iPaaS (Integration), dvPaaS (Data Virtualization), bpmPaaS (Business Process Management), mPaaS (Mobile)

Amazon

AWS

• Amazon Web Services
• Web service backend providing libraries for majority of modern web programming languages
• Provides also database access and storage
• Features mobile platform as well
• REST-style HTTP, SOAP

S3

• Simple Storage Service
• Provides API-driven Object storage
• Stored files are abstracted all the way to objects and are easy to represent in high-level programming languages
• REST-style HTTP, SOAP, BitTorrent

EC2

• Elastic Compute Cloud (IaaS)
• KVM-based
• Provides backend to earlier mentioned services as well as ability to sell „Virtual private cloud“ to customers
• OSs (Linux, OpenSolaris, Windows, NetBSD, …)

Other

• Elastic Beanstalk (PaaS)
• AWS Lambda (event-driven, serverless computing - FaaS)
• Glacier (storage for archives or backups)
• Elastic Block Store (block-level storage)
• SimpleDB, DynamoDB, Elastic MapReduce, …

Google

Cloud Platform

• Rich platform exposing functionality over REST
• Primarily developed to support Google's core services (search, youtube, gmail)
• Later extended with the business needs driven by Android, its integration with services
• Nowadays featuring rich set of programming frameworks, hosting services and database engines

App Engine

• Web apps on Google's infrastructure (PaaS)
• Python, Java (JVM), Go, PHP, Node.js
• Easy deploy, monitoring, scaling
• Limited languages and tools (SQL vs. GQL)

Compute Engine

• IaaS
• Compute Engine Unit (GCEU) - abstraction of computation power
• at the backend kvm based

Storage

• IaaS for storage
• REST-like HTTP access
• compatible with Amazon S3

BigQuery

• web service (with REST-like interface)
• work with Storage
• SQL dialect, returns JSON
• can be integrated via HTTP (Spreadsheets)

Red Hat

• Provider of solutions that can serve either as a private or public cloud
• Also provider of PaaS/xPaaS solution (OpenShift)
• Involved in development of cloud-oriented apps ranging from Level 1 (kernel, KVM), through management software (OpenStack, oVirt) and PaaS up to application level (Jboss Enterprise Application Platform, Data Virtualization, etc.)

oVirt

• open source upstream for Red Hat Virtualization
• can manage networks, CPUs, storages
• with VM it can do live migration, live snapshots
• integrate with many open source projects (OpenStack, Foreman, ManageIQ, …)

oVirt Engine

• Java (GWT, WildFly)
• REST-style HTTP API
• can integrate with LDAP or AD

oVirt Node

• RHEL, CentOS, Fedora or Debian with KVM
• VDSM (Python daemon) manages resources and VMs
• gets commands from Engine and reports back to it

OpenStack

• open source platform for cloud computing (mainly IaaS)
• written in Python
• each Project aims to solve one part of cloud computing needs
• pluggable w/r/t backends and between Projects

Identity (Keystone)

• central user management and authentication service
• can use directory service backend (LDAP)

Compute (Nova)

• layer on top of hypervisor(s)
• manages compute resources - VMs and containers

Networking (Neutron)

• manages networks and IP addresses for VMs
• can use SDN technologies (OpenFlow)
• load balancing, floating IPs, firewall, VPN, …

Other

• Block Storage (Cinder) - many storage providers
• Image Storage (Glance) - images to boot from and to store snapshots of VMs to
• Orchestration (Heat) - used to manage deployments of applications on OS
• Database as a Service (Trove)
• Bare Metal (Ironic) - management of physical machines (PXE and IPMI as default)

OpenShift

• PaaS
• container based deployment and management
• Kubernetes with Docker images
• written in Go

IBM

SoftLayer

• IaaS
• Servers (Bare Metal, Virtual)
• Storage (Block, File, Object, Backup)
• Networking (VPN, DirectLink, CDN)
• Management (Monitoring & Reporting, Managed Hosting)

Bluemix

• PaaS
• based on Cloud Foundry
• runs on SoftLayer
• supports Java, Node.js, Go, PHP, Swift, Python
• include OpenWhisk (similar to Amazon Lambda or Google Cloud Functions)

Heroku

• PaaS
• Ruby, Java, Node.js, Scala, Clojure, Python, PHP, and Go
• PostgreSQL, Redis, MongoDB
• Connect for Salesforce

Cloud Foundry

• PaaS
• Ruby, Go, Java, Node.js, Python, PHP, .NET
• IBM, Pivotal, HPE, GE, Huawei - certified providers

Recap

• not a full enumeration of subjects on market
• offerings are different in technologies, services and prices
• offerings often overlaps in a lot of parts
• offerings often provides some added value for allied services / products
