There are strong synergies between Open Source Software (OSS) and cloud computing. The cloud makes it a great platform on which OSS business models ranging from powering the cloud to offer OSS as SaaS can flourish. There are many issues around licenses and IP indemnification and discussion around commercial open source software strategy to support progressive OSS business models. I do see the cloud computing as a catalyst in innovating OSS business models. Powering the cloud: OSS can power the cloud infrastructure similarly as it has been powering the on-premise infrastructure to let cloud vendors minimize the TCO. Not so discussed benefit of the OSS for cloud is the use of core algorithms such as MapReduce and Google Protocol Buffer that are core to the parallel computing and lightweight data exchange. There are hundreds of other open (source) standards and algorithms that are a perfect fit for powering the cloud. OSS lifecycle management: There is a disconnect between the source...

Earlier this week I announced that I will be presenting at SYS-CON's 2nd International Cloud Computing Conference & Expo in New York City this coming March 30-April 1, 2009. During the Cloud & the Government Session at Cloud Computing Expo I will discuss the results of a new survey on cloud computing in the Federal government. Federal government organizations have typically been viewed as cautious adopters of new technologies. However, as expressed by now President Obama's transition team , cloud computing has captured the attention of many government IT decision makers. The U.S. Defense Department’s Defense Information System Agency is, in fact, already fielding a cloud computing infrastructure. In October 2008, through on-line surveys and in-depth interviews, customer requirements and concerns were gathered in order to shed light on current cloud computing offerings targeted for government customer. In February 2009, the survey will be repeated in order to gauge how...

Today's announcement by CSC reinforced the strong wave of cloud computing towards the Federal space. Ranked by Washington Technology Magazine as 9th largest (by contract dollar value) government contractor, this practically guarantees a bloody battle over the Federal cloud market. "Together, CSC and Terremark will offer cloud services that include computing, storage and disaster recovery/continuity of operations that are delivered from a highly secure and reliable environment, located at Terremark's datacenter in Culpeper, Va. 'Terremark and CSC look forward to delivering a portfolio of cloud computing resources that will allow our government customers to implement IT services for mission-critical applications in minutes, not days," said Jamie Dos Santos, president and chief executive officer of Terremark Federal Group. "Instead of buying costly, cumbersome hardware, this offering provides the customer access to a resource pool of processing, storage and ne...

TCP/IP uses 32 bits, or four numbers between 0 and 255, to address a computer. IP Addresses Each computer must have an IP address before it can connect to the Internet. Each IP packet must have an address before it can be sent to another computer. This is an IP address: 192.68.20.50 This might be the same IP address: www.w3schools.com An IP Address Contains 4 Numbers. Each computer must have a unique IP address. This is your IP address: 196.217.223.127 TCP/IP uses four numbers to address a computer. The numbers are always between 0 and 255. IP addresses are normally written as four numbers separated by a period, like this: 192.168.1.50 . 32 Bits = 4 Bytes TCP/IP uses 32 bits addressing. One computer byte is 8 bits. So TCP/IP uses 4 computer bytes. A computer byte can contain 256 different values: 00000000, 00000001, 00000010, 00000011, 00000100, 00000101, 00000110, 00000111, 00001000 .......and all the way up to 11111111. Now you know why a TCP/IP...

TCP/IP is a large collection of different communication protocols. A Family of Protocols TCP/IP is a large collection of different communication protocols based upon the two original protocols TCP and IP. TCP - Transmission Control Protocol TCP is used for transmission of data from an application to the network. TCP is responsible for breaking data down into IP packets before they are sent, and for assembling the packets when they arrive. IP - Internet Protocol IP takes care of the communication with other computers. IP is responsible for the sending and receiving data packets over the Internet. HTTP - Hyper Text Transfer Protocol HTTP takes care of the communication between a web server and a web browser. HTTP is used for sending requests from a web client (a browser) to a web server, returning web content (web pages) from the server back to the client. HTTPS - Secure HTTP HTTPS takes care of secure communication between a web server ...

Email is one of the most important uses of TCP/IP. You Don't When you write an email, you don't use TCP/IP. When you write an email, you use an email program like Lotus Notes, Microsoft Outlook or Netscape Communicator. Your Email Program Does Your email program uses different TCP/IP protocols: It sends your emails using SMTP It can download your emails from an email server using POP It can connect to an email server using IMAP SMTP - Simple Mail Transfer Protocol The SMTP protocol is used for the transmission of e-mails. SMTP takes care of sending your email to another computer. Normally your email is sent to an email server (SMTP server), and then to another server or servers, and finally to its destination. SMTP can only transmit pure text. It cannot transmit binary data like pictures, sounds or movies. SMTP uses the MIME protocol to send binary data across TCP/IP networks. The MIME protocol converts binary data to pure text. POP -...

TCP/IP is the communication protocol for the Internet. Computer Communication Protocol A computer communication protocol is a description of the rules computers must follow to communicate with each other. What is TCP/IP? TCP/IP is the communication protocol for communication between computers on the Internet. TCP/IP stands for T ransmission C ontrol P rotocol / I nternet P rotocol. TCP/IP defines how electronic devices (like computers) should be connected to the Internet, and how data should be transmitted between them. Inside TCP/IP Inside the TCP/IP standard there are several protocols for handling data communication: TCP (Transmission Control Protocol) communication between applications UDP (User Datagram Protocol) simple communication between applications IP (Internet Protocol) communication between computers ICMP (Internet Control Message Protocol) for errors and statistics DHCP (Dynamic Host Configuration Protocol) for dynamic addressing TCP Uses a ...
