DO NOT confusion with '''Cloud Computing''' and '''Cloud Computing Comparison'''

This article consolidates, concise and compare Cloud Computing Utility Service providers based on computing technologies (referred as Features) advantages they provide and utilized in their service provision. Features would optimize our day-to-day IT operations and impacts on our ability to perform and deliver IT services/ products to our Customers/Consumers. This article would enable users to distinguish amongst the vendors based on the features that each of them provide.

This article requires continuous updates for any changes/ upgrades in Features (computing technology) or any new player prominently getting added into cloud utility business. Hence a sincere request to all – kindly modify/update the tables below.

Please refer to Cloud Computing before reading through this article, to understand the fundamentals of Cloud Computing technology.

Cloud Computing Utility Providers[edit]

Features of Cloud Computing[edit]

Computing Technologies are been referred as Features in this article.

Features Description
ACID [1] Atomicity, Consistency, Isolation, Durability for DB
AMQP [2] Advanced Message Queuing Protocol
Asynchronous transmission [3] Asynchronous transmission uses start and stop bits to signify the beginning bit[citation needed] ASCII character would actually be transmitted using 10 bits, the extra one (or zero, depending on parity bit) at the start and end of the transmission tells the receiver first that a character is coming and secondly that the character has ended.
BASE [4] Basically Available, Soft state, Eventual consistency
BigCouch [5] allows users to create clusters of CouchDBs that are distributed over an arbitrary number of servers, While it appears to the end-user as one CouchDB instance
Blobs [6] Binary Large Object
Bootstrap [7] System following a standard protocol once booted
Cascading [8] used to create and execute complex data processing workflows on a Hadoop cluster
CIDR [9] Classless Inter-Domain Routing
Cluster [10] Group of servers
CNAME [11] Canonical Name record in DNS
Columnar [12] A column-oriented database serializes all of the values of a column together, then the values of the next column, and so on
Degaussing [13] process of decreasing or eliminating a remnant magnetic field
Edge Cache [14] pushing computing away from centralized nodes to the logical extremes of a network
Elasticity [15] to adapt to workload changes by provisioning and deprovisioning resources in an autonomic manner
Ephemeral Storage [16] transitory, existing only briefly storage
Eventual consistency [17] distributed computing that informally guarantees that, if no new updates are made to a given data item, eventually all accesses to that item will return the last updated value
Federated Users [18] A federated identity in information technology is the means of linking a person's electronic identity and attributes, stored across multiple distinct identity management systems
IaaS Infrastructure as a Service
Infiniband [19] InfiniBand is a switched fabric computer network communications link used in high-performance computing and enterprise data centers
IP Spooling [20] creation of IP packets with a forged source IP address, with the purpose of concealing the identity of the sender or impersonating another computing system
JSON [21] JavaScript Object Notation
Memcached [22] reduce the number of times an external data source must be read
MFA [23] Multi Factor Authentication
MPP [24] Massive Parallel Processing
Multipart Upload File uploaded in parts in parallel
Multi-tenancy [25] sharing of resources and costs across a large pool of users
PaaS Platform as a Service
Packet Sniffing [26] intercept and log traffic passing over a digital network or part of a network
RAID [27] redundant array of independent disks; Data is distributed across the drives in one of several ways
REST [28] Representational State Transfer
SaaS Software as a Service
Scale Up/Out [29] Create a replica of a predefined Virtual machine
Server Cloning [30] Ability to copy and clone an existing server's configuration in the cloud utilize for application/database/webserver. Instead of creating a new from scratch just copy the existing one. This helps in DR, BCP as well.
Service Registry an API-driven cloud service built to keep track of your services and store configuration values, which allows you to react to changes faster and make your application or service more highly-available. Service Registry built on top of Apache Cassandra and Apache ZooKeeper
Sharding [31] Horizontal partitioning is a database design principle whereby rows of a database table are held separately, rather than being split into columns
SOA [32] Service Oriented Architecture
SOAP [33] Simple Object Access Protocol
SSD [34] Solid State Drives
Sticky sessions [35] Sticky session refers to the feature of many commercial load balancing solutions for web-farms to route the requests for a particular session to the same physical machine that serviced the first request for that session. Since requests for a user are always routed to the same machine that first served the request for that session, sticky sessions can cause uneven load distribution across servers
STS Security Token Service
Synchronous Transmission Synchronous transmission uses no start and stop bits, but instead synchronizes transmission speeds at both the receiving and sending end of the transmission using clock signal(s) built into each component
Webmethods Glue [36] provide web services/SOAP capabilities to existing Java and C/C++ applications
