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
1
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
2
• 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)
3
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
4
• 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)
5
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 Func-
tions)
Heroku
• PaaS
• Ruby, Java, Node.js, Scala, Clojure, Python, PHP, and Go
• PostgreSQL, Redis, MongoDB
• Connect for Salesforce
6
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
