I have some personal and professional experiences , that makes me look at the clouds and see beyond the forms , something a little different .
I say it was in 2001 , with the installation of my ADSL connection 256Mbit took my effective participation in the cloud , say , the Internet, that’s when I started to have a place on the Internet I could call my own , a fixed IP , 200 171 183 ….
While everyone was happy to have a stable and ” fast ” connection to access the Internet somewhere I was happy to have a place on the Internet that could be accessed from anywhere .
When I took possession of this ” site” on the Internet , I had already registered domains , websites provider, email with own domain , virtual drive on the internet and almost everything that was necessary for my business consulting and training , but still lacked all this being in my ” place ” to set an example when did presentations of my work for clients and prospects , then working with consultants on LINUX OS and implementation of services for open standard technologies .
Well , despite the place being Virtual Internet (Fixed IP ) , it was necessary to materialize some physical things in the real world as :
A machine with server features that could be connected 24 × 7 and allowing some flexibility . I started with good server board with a 933MHz Intel 1xP3 and 512 Mb RAM and 40 Gb HD and with time , full fitted with 2xP3 933MHz and 2Gb RAM and 500 GB 4xHD , ! and
A safe to accommodate the computer where access was restricted , but at the same time easy for those who had the privilege , and that was airy and guaranteeing the stability of the physical power connections , network and telephony to stay connected 24 × place 7 , 365 days a year. Anyway , I chose a corner under the desk in my home office .
As the needs of software initially started with :
S.O. GNU / Linux ,
A script protection , firewall ( iptables ) and
secure remote connection ( SSH ) for administration with SSH public / private key server .
Thus , he had a point on the Internet , with full access and secure, and gradually , as the demands I could go configuring the most appropriate way and creating my applications and examples .
And the demands began immediately , with the need to access the information I stored in the Home Office :
Handbooks and manuals ,
floppy images and
Installation files .
A great opportunity for a configure a storage space therefore had need to access that information in different ways , sometimes the client was sometimes Linux console browser on Windows , sometimes I was even accesses and other I sent link and someone was downloading or sending files via upload , finally the files were the same , but had access control and various presentations to meet varied and user access . For this I used :
connection for secure transfer ( SFTP )
traditional FTP service ,
one file manager in PHP to access via browser , requiring a web server ( apache ) .
Further , taking advantage of my independence and mobility, service demands became more elaborate and to meet them installed a server database to store the information in machinery of my clients , their settings and system for monitoring demands . At the time , I researched and installed another PHP script called IRM ( Information Resources Manager ) , leveraging Apache already installed in the same way , the service database was used to support various other applications such as:
Forum for tips ,
Photo gallery ,
Blogs and etc. .
For these sites and web applications could work properly had to configure some services . It was necessary to install various infrastructure services , starting with a DNS server , the DNS slave server in a trusted friend . And finally with this infrastructure available, unable to migrate my domain to my Hosting Home to support all this counted with the following services platform :
name , DNS,
Web , HTTP and HTTPS
E- mail , SMTP and SMTPS ,
Transfer files , FTP ,
Secure Virtual Network , VPN ,
Recovery Emails POP3 and POP3S and
And access to IMAP and IMAPS .
There was such an amount of integrated services and applications on the server when I did presentations , customers wanted to know how much was staying there, your websites , emails , applications ….. there in my Home DataCenter .
Given the demand for infrastructure services by some clients , just taking some well occasionally.
Put another HD and increased my storage , I isolated partitions with LVM , created some backup routines , access management , recompile the kernel and implemented the UML ( User Mode Linux ) something like virtualization in 2003 with some virtual machines serving small demands .
Ten years have passed and there have been significant changes in supply , quality and quantities involved , bands Megabit to Gigabit , Megabyte for TeraByte storage , processing, multi -processor multicore , multiple types of access to multiple access devices , mobility and more .
But , just as clouds are formed of water , H20 , no matter their shape , height and color , the basic unit that gives life to all of this technology is the bit , assuming only two states , 0 or 1 .
This, leads me to think , and even philosophize about what are really the new structures have been and are being created , which , fundamentally , in small departments and functions fit together like Legos ® to form a major element .
I have no doubt that Cloud Computing is more than this , and it’s a new paradigm , but it is also good to know that in the same way that clouds are made of the h20 Cloud Computing is also made from bits and bytes grouped into small pieces will be used to mount all this innovation in Information Technology which is the Cloud Computing .
Well , to finish the story , I don´t have a company of Cloud since 2009 and all my domains , applications and data are GoogleApps or EC2 or AWS , and in 2011 , I disabled my Internet server under the table and turned MídiaServer Home , after more than two dozen home networking devices , Internet of Things , is starting to take space there .
