Top 5 IT Job Trends: Skills & Certifications
Today, end users have different expectations of their IT departments than they previously did. Large developments in networking capacity, media streaming, data processing, and the Internet, in general, have accounted for very different preferences.
These trends will most likely continue and IT administrators should prepare by having a well-rounded IT team. This is becoming the norm regardless of company size or type of organization. Highly skilled workers are a hot commodity, especially in this field. Here are the top 5 skills with certifications and jobs that match what every IT department is looking for in their team.
1. Network Administration
Any complex data center lives or dies on the efficiency and dependability of its data network. Failure of a physical server, connection, switch, or router can be costly when it disconnects end users, automated factory floors, or online retail operations from vital IT functions. All of this increases the need for strong network management to provide vital information for planning and testing healthy networks and the environments they serve. The amount and type of network traffic can provide important clues as to the kinds of hardware and software necessary to run an operation efficiently. The ability to knowledgeably choose the correct hardware, implement connections, and work with the software are highly specific skills.
Network administration covers a broad spectrum, but a solid understanding of TCP/IP, DNS, and related technologies (i.e., load balancing and NTP) are key. It seems that because of the volume and speed with which companies are adopting new technologies, such as virtualization and the cloud, hands-on practical networking experience is preferred by hiring managers, but certifications can’t hurt!

2. Cybersecurity
Malicious software, Distributed Denial of Service (DDOS), cyber attacks – these represent the reality of corporate computing today. Moreover, IT professionals must always be aware of internal security issues, from the mundane to the complex as well as understanding the vulnerabilities within their own networks, from operating systems and servers to basic hardware and cabling. While it’s good to specialize, it’s obvious from the breadth of these examples that having knowledge and capabilities across a broad security spectrum can make a difference in any IT department.
A few valuable security skills include expertise in identity and access management, threat/vulnerability assessment, encryption, data loss prevention, incident analysis, governance, compliance and auditing, biometrics, and Web content filtering. Today, it’s increasingly common to outsource the more technical and sensitive areas to security specialists, but it’s also important to pre-empt attacks and possible data loss with in-house capabilities. In terms of security, IT must have the necessary ability to make good decisions about the security portfolio, and this requires a certain level of security competency in some, or all, members of an IT team.

3. Project Management
It’s interesting to note how this skill that might normally fall under production or administration responsibility is now considered essential for IT. For example, when you consider the number of advanced projects that IT has had to undertake, from virtualization implementation and cloud integration to storage increases, Disaster Recovery (DR), and Unified Communications (UC), the need for this skill is understandable. Every one of the new technologies IT is expected to implement consists of many complicated moving parts with hard deadlines and benchmark targets that have little room for compromise or failure.
When you consider that most if not all companies will expect normal business functioning during implementations, the need for precise, capable scheduling, prioritizing, and goal-setting is understandable. IT project managers, or IT team members who possess this skill must have an understanding of the business on a larger scale as well as thorough knowledge of the IT world. IT is the locus for technology development and the complex technical initiatives companies undertake. Having competency in this skill set will be in demand as companies continue to upgrade their technology environments to keep pace with new innovations as well as with their competitors.
Certifications related to this skill:
Project Management Professional (PMP)
Certified Associate in Project Management (CAPM)
Most common job titles:
Project Manager
Project Analyst
4. Virtualization
Virtualization means converting multiple physical servers to virtual machines (VM). This experience and the ability to convert non-virtualized environments into virtual ones is closely tied to networking abilities. When you partition one physical server into several VMs, you can deploy, operate, and manage multiple operating system instances at once on that single physical server and, consequently, save on a variety of costs. Some of the related skills that are important to have in this area are server maintenance, application development, storage allocation, and security.
In terms of cloud computing, a primary goal is to reduce the cost of computing resources while increasing system flexibility and scaling. During and after cloud implementation, there are a number of skills that are invaluable. These include scaling expertise which requires a unique ability to design and implement cloud-scale applications. A master integrator skill enables one to build best-of-breed hybrid solutions that consume elements from many different sources, both public and private clouds.
Another key cloud-based skill is Application Programming Interface (API) knowledge. Designing or implementing an API is part science and part art, and highly specialized. Anyone with this skill would be a solid addition to an IT team. Finally, skill as an automation wizard means having familiarity with the design and implementation of automated systems.
To fulfill the ideal of fast access to cloud services, automation is crucial and so is the ability to work with these systems.

5. Business Analysis
IT plays an extremely valuable role in business. As overall data levels rise, business intelligence and data warehousing skills that enable professionals to gather and effectively analyze increasing amounts of data from various streams are also in demand. Moreover, instead of just focusing on cost savings, companies are investing in technology that provides access to, and analysis of, real-time data, enabling better business decisions.
This move from process-centric to data- and memory-centric computing is already having an impact on current computing trends. IT is expected to adopt a completely new approach to understanding data sets. Team members will be expected to possess new capabilities to perform fast, efficient data analysis. It will also require new hardware and software implementation skills as well as the ability to run and maintain them.
Certifications related to this skill:
EC-Council Training (CEH, ECSA, CHFI)
CompTIA (CSA+)
Project Management Professional (PMP)
Most common job titles:
Business Analyst
Information Technology Manager
Business Systems Analyst
Today, business analysis, data mining, and modeling capabilities are worthwhile skills to possess in any IT department. For example, conceptual modeling of the business view of the solution is a critical tool to help bring business, technology, and delivery groups together in defining solution scope.
In addition to an ability to communicate details and concepts, critical thinking and sometimes system thinking are also key. These mean taking something large, ambiguous, and abstract and breaking it down into smaller pieces, patterns, and views within a business context.
Finally, focusing on risks to the business value of the solution and communicating that risk to shareholders is another vital skill that IT team members need to have in regards to performing an effective business analysis.

How to Get Faster Internet Speed Using DNS Hack
There are times when your internet connection is fine but you’re still not able to open any website. One of the possible causes could be the issues with your ISP’s DNS server. Configuring a custom DNS server on your make contribute to make your internet faster and load websites quickly.
There are many ways to get a faster internet speed in Microsoft Windows. Today, I am going to show you a simple DNS hack that can speed up your web browsing considerably. Before that, I need to remind you an obvious thing that happens with most of us when we are using a slow internet connection.
The only thing we blame is our Internet Service Provider (ISP) for slow internet connection, but this isn’t the only case all the time. Sometimes, the problem is related to the default DNS (Domain Name System) used by the ISP. So, let me explain you something about DNS before telling you the method to get a faster internet speed.
What is DNS?
DNS – Domain Name System – is a naming system that is used to convert the domain names into IP addresses. The domain names are usually alphanumeric for us to remember quickly, but in actuality, the Internet works on IP addresses. The DNS server, for a domain name, returns its corresponding IP address when requested by your computer (client).
The DNS has a network of its own i.e. one DNS server can ask other DNS servers about translating a particular domain name to its corresponding IP address till it gets the correct result.
Computers and other devices make use of IP address to route the traffic, and it is very much similar to dialing a phone number. DNS acts as an intelligent operator that helps us bypass the infinite address book of IP addresses. Your DNS manages this enormous task. You can read more about DNS and how it works in our detailed post.
How an Alternative DNS Service Will Speed Up Your Browsing?
As I mentioned earlier, your tortoise-like internet speed isn’t always your Internet Service Provider’s fault. Instead, it may be because of an inefficient DNS server. So why not use an alternative DNS service? As the present web pages continue to become more and more complicated by inculcating innumerable things, clients go for multiple DNS lookups for rendering one single web page. With the internet blowing up size by the clock, the existing DNS infrastructure is under more load each day.
Now, I’ll tell you to use free public DNS services that will ask your computer to use custom DNS servers instead of the default DNS server from your ISP. It will help you to get a faster internet speed.
How To Speed Up Web Browsing Using DNS Hack?
To get faster internet speed, I’d like to tell you about OpenDNS. You can also use Google DNS for speeding up your internet. OpenDNS is one of the most popular free DNS services that was started to provide an alternative method to the users who weren’t satisfied with their existing DNS servers.
How to configure OpenDNS in Microsoft Windows?
By following the steps mentioned below, you can set OpenDNS as the preferred DNS server in Microsoft Windows. This will allows various applications to perform nslookup using OpenDNS rather than your ISP’s default DNS servers.
1. To get a faster internet speed using OpenDNS, open Control Panel.
2. Go to Network and Sharing Center.
3. Here, click the name of the network connection, be it WiFi or Ethernet
4. On the next window that pops, click Properties.
5. Click the Internet Protocol Version 4 (TCP/IPv4) and click on Properties.
6. Now click Use the following DNS server addresses radio button and enter the addresses given below to get a faster internet speed
Preferred DNS server: 208.67.222.222
Alternate DNS server: 208.67.220.220
If you want, you can interchange these addresses. Click OK to save and continue.
How to configure IPv6 custom DNS:
Since the adoption of IPv6 addresses is on the rise, it’s time you should configure iPv6 DNS servers as well. Highlight the Internet Protocol Version 6 (TCP/IPv6) and click Properties.
Choose the following DNS server addresses:
Preferred DNS server: 2620:0:ccc::2
Alternate DNS server: 2620:0:ccd::2
How to configure Google Public DNS in Microsoft Windows?
Replace those addresses with the IP addresses of the Google DNS servers in step 6.
For IPv4: 8.8.8.8 and/or 8.8.4.4.
For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844
Conclusion
In a nutshell, OpenDNS, Google DNS are reduce the time taken to resolve the domain name on the web and make the internet faster in the process. Obviously, it won’t increase the maximum available bandwidth for your connection. Moreover, they are more reliable than the default ones used by your ISP. Do I need to mention one of them is maintained by Google? These custom DNS servers face downtime, due to power outages or some other hardware issues, less often.
Both Google DNS and OpenDNS work just fine but people prefer Google DNS these days. You can choose to go for any of these and see if your internet speeds up.
Why Does 64-Bit Windows Need Two Program Files Folders — Program Files & Program Files (x86)
Ever wondered why 64-bit Windows needs to have two Program Files folders? This is done to separate the 32-bit DLL executables from 64-bit DLLs. It also eliminates the chances of a 32-bit application trying to load a 64-bit DLL, fail, and give an error message.
Back in 2005, Microsoft launched both 32-bit and 64-bit versions of Windows operating system. This was done to support new 64-bit CPUs. The 64-bit CPUs have the ability to work with large numbers and access more memory.
If you’re running 64-bit Windows operating system, you might have noticed that your PC has two Program Files folders. One is the regular Program Files and the other one is Program Files (x86). But, why is it necessary? What’s the difference between these two folders?
Well, to answer these questions, one should understand that 64-bit applications are compiled differently. While a program with 64-bit instructions can’t be read by PCs with 32-bit CPUs, a 32-bit program can be read by 64-bit CPU.
Windows has a separate Program Files (x86) folder, Why?
Whenever you install any program on a computer with 64-bit CPU, its folders are, more or less, intended for 64-bit content. When a 32-bit program tries to use a 64-bit component, it faces some problems.
So, Windows separates the directories of 64-bit and 32-bit programs. The Program Files (x86) is the one for storing 32-bit program. x86 stands for the type of processors — 286, 386, 486, 586(Pentium).
Another reason is that 64-bit software doesn’t act nicely with 32-bit extensions, and vice versa. It increases the chances of a conflict if you happen to install both 64-bit and 32-bit versions of a program on the same system.
Last but not the least, having two separate Program Files folders ensures that 32-bit applications, unaware about a 64-bit system, work. Separating both kinds of applications will eliminate the chances of a 32-bit application trying to load a 64-bit DLL, fail, and give an error message.
Apart from the Program Files, there are some other Windows components that have both 32-bit and 64-bit copies. Some of these are stored in winsxs (stands for windows side by side) and syswow64 (Windows 32 on Windows 64).
