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 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
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
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, . . . )
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, . . .
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
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)
IaaS
Compute Engine Unit (GCEU) - abstraction of computation
power
at the backend kvm based
IaaS for storage
REST-like HTTP access
compatible with Amazon S3
web service (with REST-like interface)
work with Storage
SQL dialect, returns JSON
can be integrated via HTTP (Spreadsheets)
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.)
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, . . . )
Java (GWT, WildFly)
REST-style HTTP API
can integrate with LDAP or AD
RHEL, CentOS, Fedora or Debian with KVM
VDSM (Python daemon) manages resources and VMs
gets commands from Engine and reports back to it
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
central user management and authentication service
can use directory service backend (LDAP)
layer on top of hypervisor(s)
manages compute resources - VMs and containers
manages networks and IP addresses for VMs
can use SDN technologies (OpenFlow)
load balancing, floating IPs, firewall, VPN, . . .
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)
PaaS
container based deployment and management
Kubernetes with Docker images
written in Go
IaaS
Servers (Bare Metal, Virtual)
Storage (Block, File, Object, Backup)
Networking (VPN, DirectLink, CDN)
Management (Monitoring & Reporting, Managed Hosting)
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)
PaaS
Ruby, Java, Node.js, Scala, Clojure, Python, PHP, and Go
PostgreSQL, Redis, MongoDB
Connect for Salesforce
PaaS
Ruby, Go, Java, Node.js, Python, PHP, .NET
IBM, Pivotal, HPE, GE, Huawei - certified providers
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 /
