Development Architecture blog is designed for developers who have some troubles in their code.
This blog will be mainly on web development, though many of it's posts can be used also on software design.

Cloud Computing Advantages and Disadvantages
Cloud computing was introduced this week as a giant client server
environment. Analyze the advantages and disadvantages of computing on
Cloud computing refers to anything that is involved in
delivering host-based services on the Internet. The services are of three types:
IaaS (Infrastructure-as-a-Service), PaaS (Platform-as-a-Service), and SaaS
(Software-as-a-Service). The term ‘cloud computing’ is derived from the symbol of
the cloud that often describes the Internet in flowcharts and diagrams.
Recently, cloud computing has become one of the most hyped
information technology topics of the decade (Enslin 2012). With cloud computing
one can access documents and applications from any part of the world. This
frees you from being bound to your computer at home. Miller says that cloud
computing is definitely not for everyone (Miller 2009). There are advantages
and disadvantages to this type of internet computing.
While analyzing the advantages, Miller says computing on the
internet results in lower IT infrastructure and software costs. This is
because, to handle their peak needs companies will not need to invest in more
powerful servers and equipments to handle the peaks. If the IT department uses
the computing power of the cloud to supplement internal computing resources, the
peak needs can be easily handled by servers and computers in the cloud. As for
software costs, with cloud computing IT staff are saved the cost of installing
and maintaining the software programs on every computer in the organization
Cloud computing also results in enhanced service
accessibility. This means that with this technology one can access services
that are otherwise unavailable. The vast majority of the function is performed
on the server-side, which means the user can run on a device with very little
capacity. This has opened up countless possibilities in the forms of mobile
phone and hand-help computers. This enables one to gain access to services from
multiple device types, whether laptops, desktops, mobile phones, and so on (Clarke
2009). Clarke further talks about the technical advantages of cloud computing
including professional backup and recovery, collaboration convenience,
scalability, and copyright convenience.
One may think that with all these benefits, cloud computing
may not have any disadvantages. However, that is not true. One of the main
limitations is that it requires high-speed internet connection at all times. A
lot of good features of portable computing create issues when you’re depending
on web-based applications. To solve this problem, certain web-based
applications are now being designed in such a way that one can work on a
desktop with internet connection. An example is Google Gears, which converts
Google’s web based applications to locally run applications (Miller 2009).
According to Miller another issue is the security of the
data on the cloud. There are possibilities of unauthorized access to your data
that is stored in the cloud. In addition, although the data is generally safe,
but if it happens to somehow get deleted, there is no way to create a backup.
In such cases, people generally lose all their information. Another
disadvantage that is subject to change in the near future is the limited
features of internet computing. Today not all web-based applications have the
unique features that their traditional desktop applications have.
As with everything else, cloud computing has its pros and
cons. Users must appreciate the advantages, disadvantages, and risks and then
carefully consider how it can be applicable to their specific needs (Clarke
2009). Wherever cloud computing is adopted, risk management must be planned and

Protecting personal data can be overwhelming, but it is not impossible. There are highly secure tools both online and offline to protect personal data. Shielding personal data can be logical, highly secure as well as inexpensive. Protecting Personal Data Offline Physically lock your financial records and personal documents in a safe place in your home. Purchase an inexpensive fire-proof safe that can be stored in a secure closet, built in your floor or wall. A good fireproof safe costs from $100 to $3000 (Sears, 2013). Protect your wallet and or purse in a desk drawer at work. Limit what you carry when you go out. Never keep your social security card in your wallet; lock it up. When filling out forms in the workplace, the doctor’s office, or your child’s school ask how your information will be safeguarded. If you do not have to fill out every little detail of your life, leave that portion blank. Ask for the consequences of not providing specific information. Shr
Behavior Driven Development, Test Driven Development, and Everything Between What is TDD (Test Driven Development) Test Driven Development was introduced by Kent Beck, in 2003. This followed the concepts of Extreme Programming, introduced in 1999 with a development experiment done by both IBM and Microsoft. The purpose of the Test Driven Development is to make sure code is clear, tested, and as redundant as possible, by making sure the tests are written first, and code is being added to "fill the blanks". Every code iteration needs to pass all tests (may those be unit tests, integration tests, data integrity tests, or UI tests). Writing the tests first allow us to see what fails, how, and allow us to visualize the structure of our code, by making sure each test is performed to test a specific, extremely defined sub-section of a feature. Let's assume a "BasicMaths" class, to perform simple mathematics operations. [TestClass] public class Uni
