IaaS

Provide all the Infra to install OS
Service are only CPU Core, Memory, Disk Space
and Network bandwidth
Self service
– – Other services needed by your users


OS installation and configuration
Yes we need personal with LPI certificate
Example : Amazon EC2 and Google Compute
Engine

PaaS

Provide all the need for your software (Computing
platform)
Service include operating system (PaaS),
programming language execution environment,
database, and web server.
Self service


Programming (PHP, Python and C)
Example : Google Apps Engine (Python & Java)
and Microsoft Azure (PHP & ASP)

SaaS

Provide all the needed application services
(Email, Website, API, Security and Documents
sharing)
● We are only the users and the data is still ours
● Example : Google Apps and Cloudflare

Own Vs Cloud

Own
– – Layers (GeoServer & MapNik)
– Database (PostGIS + PostgreSQL)
– Web Map Server (WMS) (Apache + Jboss + Nginx
   + Varnish)


Basemap (GeoServer & MapNik)
Client & Web browser (Qgis & Mozilla Firefox)
Cloud
– Basemap, Layers, Database, WMS (Google Map
   API)
[email protected]

Open Source drive the Cloud
Amazon EC2, Google, Cloudflare & OpenDNS
are using Open Source

Center (capable of scaling to several petabytes
(actually, 72 brontobytes!)
● Easy setup and use of commodity hardware
● Scalability and Elasticity
● Simplicity
● Open Source and support by Red Hat

Gluster Connector for OpenStack – Underlying
file system.

Check Your Email Sender Authentication Schemes

Check Your Email Sender Authentication schemes

You can email to [email protected] to check your email server sender authentication schemes setup. This will help you to determine the reasons your email mark as SPAM when you send email to your friends. Your email server must a least have one of them. Example Email Sender Authentication schemes are DKIM, Domain Keys, Sender ID and SPF.

New effort to combat SPAM and spoofed email.

Domain-based Message Authentication, Reporting & Conformance


Email auto respond from [email protected]

sendmail.net Sender Authentication Auto-Responder $Revision: 1.19 $

This service runs at and allows remote users
to perform a simple, automated test to see if different Sender
Authentication schemes are working.  Mail sent to this service
is checked by our Sender Authentication filters for any valid
credentials or signatures.  A script receives the message, checks
for a special header with the results of the tests, and composes
this response message based on what it finds.  This response is also
signed with DomainKeys and DomainKeys Identified Mail (DKIM).

Please note that the DKIM filter signing this reply message conforms
to the latest IETF draft version, and thus may not be successfully
verified by older implementations.  If you are using dkim-filter from
Sendmail, Inc., upgrade to at least version 1.0.0 to be compatible
with the most recent version of DKIM.

We hope this service has been helpful to you.
