Cloud computing is Internet- ("cloud-") based development and use of computer technology ("computing"). In concept, it is a paradigm shift whereby details are abstracted from the users who no longer need knowledge of, expertise in, or control over the technology infrastructure "in the cloud" that supports them.Cloud computing describes a new supplement, consumption and delivery model for IT services based on Internet, and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet.

The term cloud is used as a metaphor for the Internet, based on the cloud drawing used to depicted the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. Typical cloud computing providers deliver common business applications online which are accessed from a web browser, while the software and data are stored on servers.

These applications are broadly divided into the following categories: Software as a Service (SaaS), Utility Computing, Web Services, Platform as a Service (PaaS), Managed Service Providers (MSP), Service Commerce, and Internet Integration. The name cloud computing was inspired by the cloud symbol that is often used to represent the Internet in flow charts and diagrams.

Boeing said on dec 10,2009 that it has successfully completed the final gauntlet test on the first Boeing 787 (ZA001) and that the initial “window” for the maiden flight of a 787 is 10 a.m. PT Dec. 15. By “window,” Boeing means a tentative time that is largely dependent on the weather or last minute technical problems.


“We will not name a date certain, but rather a window of days for the flight to occur, recognizing that a number of circumstances, weather not the least of which, can pull the day forward or push it back,” Boeing spokesman Jim Proulx told me this afternoon before the DEC 10'S announcement.

Indeed, weather would seem the biggest obstacle. Weather.com’s 10-day forecast for Everett, Wash. is rain or snow showers for all but Monday next week. Tuesday is Dec. 15. Everett is the location of Paine Field where ZA001 will take off, representing the maiden voyage for the 787.

The plane is slated to fly for four hours and land at 2 p.m. PT at Boeing Field in Seattle.

All that remains before the flight are taxi and flight readiness tests and receipt of documentation from the FAA. The gauntlet test just completed simulated an actual flight. Also, Boeing said 10 days ago it needed until now to validate the side of body repair which involved reinforcing a small area where the wing attaches to the wingbox.

T certifications boast numerous benefits. They bolster resumes, encourage higher salaries, and assist in job retention. But which IT certifications are best?

Technology professionals generate much debate over just that question. Many claim vendor-specific programs best measure a candidate’s skills, while others propose vendor-independent exams are the only worthy way of measuring real-world expertise.

#1: MCITP

The new-generation Microsoft Certified IT Professional credential, or MCITP for short, is likely to become the next big Microsoft certification. Available for a variety of fields of expertise — including database developer, database administrator, enterprise messaging administrator, and server administrator — an MCITP validates a professional’s proven job-role capabilities. Candidates must pass several Microsoft exams that track directly to their job role before earning the new designation.

#2: MCTS

The new-generation Microsoft Certified Technology Specialist (MCTS) helps IT staff validate skills in installing, maintaining, and troubleshooting a specific Microsoft technology. The MCTS certifications are designed to communicate the skills and expertise a holder possesses on a specific platform.

#3: Security+

Security continues to be a critical topic. That’s not going to change. In fact, its importance is only going to grow. One of the quickest ways to lose shareholder value, client confidence, and sales is to suffer a data breach. And no self-respecting technology professional wants to be responsible for such a breach.

#4: MCPD

There’s more to information technology than just administration, support, and networking. Someone must create and maintain the applications and programs that power organizations. That’s where the new-generation Microsoft Certified Professional Developer (MCPD) credential comes into play.

#5: CCNA

The Cisco Certified Internetwork Expert (CCIE) accreditation captures most of the networking company’s certification glory. But the Cisco Certified Network Associate (CCNA) might prove more realistic within many organizations.

#6: A+

Technology professionals with solid hardware and support skills are becoming tougher to find. There’s not much glory in digging elbow-deep into a desktop box or troubleshooting Windows boot errors. But those skills are essential to keeping companies running.

#7: PMP

Some accreditations gain value by targeting specific skills and expertise. The Project Management Professional (PMP) certification is a great example.

#8: MCSE/MCSA

Even years after their introduction, Microsoft Certified Systems Engineer (MCSE) and Microsoft Certified Systems Administrator (MCSA) credentials remain valuable. But it’s important to avoid interpreting these accreditations as meaning the holders are all-knowing gurus, as that’s usually untrue.

#9: CISSP

As mentioned with the Security+ accreditation earlier, security is only going to grow in importance. Whatever an organization’s mission, product, or service, security is paramount.

#10: Linux+

While pursuing my first Microsoft certification 10 years ago, I remember debating the importance of Linux with several telecommunications technicians. They mocked the investment I was making in learning Microsoft technologies. These techs were confident Linux was going to displace Windows.
