Are you on the right cloud computing career path?

As the use of cloud computing increases within companies, jobs with cloud skills also emerge. Are you on the right cloud career path?

While the rise of cloud computing frightens some in IT, many see the technology as an opportunity to accelerate their careers and grow their bank accounts. However, those attempting to navigate their cloud careers must take specific paths, and understand certain skill sets are valued more than others.

IT pros have good reason to be optimistic about finding riches in the cloud. In the U.S. today, 3.9 million jobs are associated with cloud computing, with 384,478 of them in IT, according to Forbes. The median salary for IT professionals with cloud computing experience is $90,950. Currently, there are 18,239,258 cloud computing jobs worldwide, 40.8% of which are located in China.

There is an explosion in both cloud computing use and demand for people who can help with cloud migrations. There are about 100 jobs chasing each qualified candidate at this point in time, according to technical recruiters.

Choosing a cloud career path

There are two types of emerging cloud computing careers: IT pros with specific cloud skills and IT admins with cloud architecture know-how.

Companies that require specific cloud computing skills or development skills are typically already committed to a specific cloud provider, such as Amazon Web Services (AWS), Microsoft Azure or Google Cloud Platform. These positions are often tied to emerging DevOps automation tools and processes, and usually in newly formed enterprise groups.

As Docker and container technology trends, there’s demand for knowledge or experience building portable applications with containers.  shows the explosive growth of Docker in the last few years based on the number of job postings reported by Indeed.com.

Docker knowledge is a highly sought skill, as most cloud providers adopt this container technology. A background in container-clustering technology, such as Google’s Kubernetes and Docker Swarm systems, is also in demand.

Roles requiring specific cloud skills account for the majority of cloud computing jobs today. Job postings seeking AWS skills lead by a large margin, followed by those requiring Google and Microsoft expertise. shows an increase in job postings for AWS talent, with explosive growth over a six-year period. These jobs include configuration, development and operations positions, with salaries ranging from $110,000 to $220,000 annually, depending on location.

In the last year, Google Cloud Platform and Microsoft Azure have shown stronger growth rates, exceeding that of AWS in some respects. This led to more job openings that focus on Google and Microsoft, a trend that will likely continue as enterprises use a mix of public cloud providers. However, IBM, HP, Verizon and CenturyLink are still in the mix, generating demand for jobs related to their own cloud platforms

Building the cloud and your career

Companies with cloud architect positions seek people who can define the cloud — from business requirements to the actual cloud deployment. These jobs tend to be with companies that have yet to define their path to the cloud and need some assistance. They may be defining the use of existing private and public clouds, or building clouds from the ground up.

Typically posted as “cloud solution architect” or “cloud architect,” cloud architecture jobs require strategic knowledge of most cloud computing technology and providers, as well as the ability to form those clouds to fit enterprise goals or needs.

Cloud architecture candidates should have enterprise architecture and/or service-oriented architecture experience, with some knowledge of proper cloud computing technology use. Salaries range from $150,000 to $250,000 annually, depending on location and experience. Consulting firms typically pay the most, but these jobs require a great deal of travel, and you can bet your dance card will be full.

 


Cloud Computing and its Advantages in Education

Cloud computing – the word “cloud” is normally used in synonymous to “Internet”. So cloud computing can also be termed as “Internet based computing”. Cloud computing is the process of using remote servers to store, manage and process data thereby not to use local servers.

Cloud computing revolutionize the field of education. This article shows you the various advantages of cloud computing in education.

Cloud computing has three major uses:

  1. Software as a service
  2. Infrastructure as a service
  3. Platform as a service

Software as a service:

In this method the user can access the software for the amount which is lower than the amount required for buying a licensed product.  The Software as a Service is also provided as monthly. So the user can access the software whenever on demand.

Infrastructure as a service:

Infrastructure as a service is used to by organization in order to outsource the equipment used to support operation, hardware, servers and various other networking components. The cloud providers are responsible for maintaining and running it.

Platform as a service:

Platform as a service is another form of cloud computing in which organization can rent hardware, operating system. Customers can also rent virtualized servers and other services which are essential for running the applications.

Advantages:

There are lot of advantages of using cloud computing in schools and colleges and some of them are:

  • It helps both the teachers and students to share information via cloud. That is the teachers can upload their information or study materials directly on cloud. Then the students can access the information and can gain knowledge through it.
  • Another advantage is that the students can attend classes outside the classroom. This can be attained through cloud computing. The students can log on to space and can attend their class sessions. This helps the teachers in such a way that there is no need to manage classrooms which are packed up with hundreds of students.
  • Teachers and students can access software and various tools for free through cloud computing. Confidential information can be stored in cloud which prevents less theft that may occur.
  • Cloud computing is a low cost option for various colleges and universities. It provides high computing facilities for low cost.
  • Time consuming process like admissions can be done via cloud within fraction of seconds.

Review: Google Cloud flexes flexibility

Google’s elegant Cloud Platform makes it easy to spin up instances or simply tap Google APIs only when you need them

If one company among all companies is synonymous with cloud-centered computing, it would be Google. From the very beginning, Google built a business located somewhere in the murky depths of the Internet, and its search engine continues to be one of the most formidable engineering marvels of the modern world. When was the last time there was an outage?

It’s only natural that anyone looking to build an information-based business that spans the Internet would turn to Google and leverage all of its experience. As pioneers, if Google needed a technology, Google engineers had to develop it themselves, then deploy it. Now everyone can profit from Google’s skills and build a Google-grade system with Google-grade reliability for pennies per hour or per click.


3 cloud resolutions for 2016

Along with losing those extra pounds, think about leveraging clouds in better and more productive ways

It’s that time of year when gyms fill up with New Year’s resolution-driven people who want to get into shape. At least, that’s the idea for the first few weeks of the calendar. Perhaps it’s time to work up your IT resolutions as well, especially when it comes to supporting your cloud-based systems in new and more innovative ways.

Resolution No. 1: Set up monitoring/management that proactively looks for performance and stability issues.

Most of us who leverage public cloud(s) use the provider’s native monitoring and management capabilities. However, a more comprehensive approach and technology is typically needed to effectively keep tabs on public and private clouds in production, as well as monitor traditional systems. The idea is to use deeper analysis of the operational data coming off the clouds to proactively spot potential issues before they hinder or stop production. This is money well invested.

Resolution No. 2: Govern all services or APIs.

APIs drive the clouds — typically, RESTful Web services. Moreover, as you build or cloud-enable applications, more APIs are exposed. You need to place service governance around these APIs to control who can access them and what they can do with them. APIs are very powerful, but in the wrong hands they can cause operational damage. You need a sound cloud service governance plan, approach, and technology in place.

Resolution No. 3: Train my people.

Simply because clouds move into the enterprise doesn’t mean the enterprise is ready for clouds. Lack of training causes most of the issues happening right now with clouds. Those who operate the cloud-based system often don’t know how to do so effectively; thus, they end up learning via trial and error. A bit of training goes a long way.

Are these resolutions doable? Absolutely. They require some investment, but the value will come back tenfold.


Linux servers in the cloud — cheaper and better than ever

If you haven’t already launched a Linux server in the cloud, this might be the perfect time. Why?

because you can set one up in a matter of minutes
because you have lots of choices on what distribution you elect to use
because you just might find that a Linux servers in the cloud provide you with a very convenient way to work with commands and apps that you might not have time or opportunity to try out at work
because you can get a lot of value of out a cloud-based Unix system at a surprisingly reasonable cost, especially if you’re new to the scene (cloud providers seem to love the newbies).
and because experience in setting up and managing Linux servers in the cloud is likely to put a very colorful feather in your IT cap

Just considering Amazon’s “free tier” deal for new cloud customers, you’re likely to be amazed at what you can set up and use. In your first 12 months with EC2, you get:

750 hours of EC2 running a Linux, RHEL, or SLES t2.micro instance
750 hours of EC2 running a Microsoft Windows Server t2.micro instance
750 hours of Elastic Load Balancing plus 15 GB data processing
30 GB of Amazon Elastic Block Storage in any combination of General Purpose (SSD) or Magnetic, plus 2 million I/Os (with Magnetic) and 1 GB of snapshot storage
15 GB of bandwidth aggregated across all AWS services
1 GB of Regional Data Transfer

Many other cloud providers also provide special deals for new customers. As examples, you can get:

a free virtual server for one month at Softlayer
a free 30 day trial at CloudLinux
free micro instances for a year at Turnkey
a free seven day trial even without supplying your credit card number at CloudSigma
And, if you’re a student, you can get free servers at YellowCircle. See http://www.yellowcircle.net

There are many ways to get started with Linux in the cloud that involve little or no investment and many different cloud providers to show you the way. Yeah, they won’t all show up in Gartner’s Magic Quadrant for PaaS reports, but they’ll give you a chance to get started in the cloud and play with a variety of Linux systems and tools. And, with just a little care, you can get your Linux cloud experience for a lot less than you’d spend going out to lunch once a week.

Now, before I go any further with this, I should say that LaaS (Linux as a Service) is really not one of the acknowledged ?aaS acronyms. Linux servers in the cloud are generally considered PaaS (platform as a service) or IaaS (infrastructure as a service) offerings depending on how much control you need to exert over their configuration (the more you have to do, the more likely they’re IaaS). The distinction may not matter unless you’re setting up multiple systems in the cloud that need to interract with each other. In fact, Amazon doesn’t even use these terms to describe its EC2 offerings.

EC2 is one of the terms you’re going to hear a lot when you start moving into the cloud. EC2 is an offering from Amazon. The acronym stands for “elastic compute cloud” and the term is meant to convey how easily you can configure, control, and resize the systems you set up. You can literally launch a server (an “instance”) in a couple of minutes (less than one minute once you’ve become used to the process) and increase or decrease the capacity of your servers as needed. That’s, of course, where the “elasticity” comes in.

Linux “instances” (the term Amazon likes to use) in the cloud provide a great way to practice your Linux skills. They can be set up as development platforms to test your apps and provide a way to judge performance of those apps on systems of varying capacity. They can be set up as servers to practice your sysadmins skills or to work with tools such as MySQL or PostgreSQL. They can make it easier for you to learn a new programming or scripting language. And you can set up your server in the cloud and have your projects accessible from wherever you happen to be — at home, in your office, or on the road.

Important considerations when looking into setting up a cloud-based Linux server include:

Amazon’s free tier is certainly a big winner when it comes to getting a lot of server usage for next to nothing (“next to” because you could exceed the usage limits). To help you determine up front what your costs are likely to be beyond the free tier, Amazon provides a cost estimator that you can use to gauge what you’ll be spending. You can terminate (basically delete) an instance — thus avoiding charges — if you’re not going to need it for a long period of time and don’t mind starting again from scratch when you do. The services are only likely to be costly if you configure a large high-end server and/or configure a lot of storage.

For most, if not all, cloud providers, you will pay for the resources that you consume. The prices are usually based on a per hour charge rounded up. But the per hour charges will generally be very low. A t2.micro system at Amazon, for example, will run as low as $.013 per hour. That’s only about $2.18 a week and less than $10/month. The most modest cloud-based system at Google is a similar $.015 per hour. Of course, if you’re reading this column well past Summer 2015, these prices may have changed a bit, but I suspect they’re going to remain very appealing for quite a long time.

Amazon also provides other ways to reduce costs, claiming that you can save as much as 90% by bidding on otherwise unused EC2 instances.

If there’s any area in which “on premises” servers are significantly cheaper, it’s probably in the storage area. If your server needs a 500 GB disk, you’ll probably find that acquiring and attaching one to your on premises server is going to be quite a bit cheaper than paying for the same amount of storage in the cloud. Then again, the cloud server will likely provide a lot of built-in redundancy which you may or may not be able to provide for your on-site systems.

Still, it’s the flexibility to expand and contract storage as needed that really elevates the cloud’s offerings. It’s much harder to resize your data storage on premises. Even if you have a hefty SAN or NAS, expanding storage for a particular server is more time consuming than making those kind of changes in an environment set up to allow these kind of changes to occur all the time.

Setup Time

Setting up a Linux server in the cloud generally involves selecting the OS and size of system you want and launching it. That plus a little time configuring how you’ll connect. It’s that quick. A couple of minutes max. You might then have to wait briefly while the system is set up, but you’ll soon be able to connect to your new server and start working.

Configuring the Server

For Amazon, you can quickly set up the keys you will need to connect to your server and configure PuTTY to allow you to log in. If you’ll be logging in from a fixed IP or a known subnet, you can configure the server to only accept connections from those addresses. You can upload content using files using tools such as scp or FileZilla. This YouTube presentation does a very nice walkthrough that includes using FileZilla with Amazon EC2.

You can also get a lot of very helpful hints on how to work in the cloud through these tips pages from Bristle Software:

Tips from Fred Stluka who said “I moved all of my servers and all of my clients’ servers
to AWS in 2009 and have never looked back” carry a lot of weight!

Avoiding Lock-In

As long as you use fairly ubiquitous tools, you won’t have much of a problem. Some people prefer not to use Amazon’s Linux AMI (a Linux image provided, supported and maintained by Amazon Web Services for EC2) because this particular image is only available on Amazon, but whether or not you want to avoid it depends on what you’re planning on doing with your Linux cloud server. It has a number of considerable advantages as it comes with many packages and tools that make it especially easy to use and Amazon Web Services provides ongoing security and maintenance updates to all instances using this image.

Security

Security is especially critical if you’re putting proprietary data in the cloud, but there are numerous ways to enhance the security of your cloud services. As mentioned already, you can restrict access to particular IP addresses. You can also encrypt connections and storage volumes.

In fact, security as a reason to not move services to the cloud is rapidly and seriously losing its footing. Companies like Amazon now go to great lengths to educate their customers on their security controls. In fact, it turns out that security in the cloud is often far better than many of us can manage on internal systems. And cloud service uptime, with its built-in redundancies is incredible.

AWS availability zones (hosting in multiple locations world-wide) involve multiple data centers located in separate buildings, on separate power grids, using separate generators, and separate disaster zones — yet all within a particular region such as US East. For most of us, that level of business continuity preparation is well beyond our reach.

Why the Cloud?

It’s not just for those of us wanting to set up a personal system in the cloud. Linux cloud offerings also provide many small and medium sized businesses with all the computing power they need. There are quite a few serious and highly successful businesses today that do all of their work using servers in the cloud. One such company is AppMakr (see https://www.appmakr.com/). These cloud-based companies find that they can hire extremely talented workers regardless of where those individuals physically reside. Clouds are great for creating inexpensive systems that you use from anywhere, but they’re also great for serious large scale development and creating a working environment that appeals to talented creative people because of the flexibility they provide — not just to the servers, but to the people who work with them.

Popular Linux servers in the cloud include Ubuntu, CentOS, Suse Linux Enterprise Server and openSuse. Amazon also offers its AMI (an EBS-backed, AWS-supported image) and various Windows cloud servers are also available.

Maybe it’s time for you to spend your $10/month and see what it’s like.

Cloud Computing in Enterprise

One of the main reasons why cloud computing is aggressively being developed is the enterprise or the business setting. Many businesses, large and small, have come to realize the potential of cloud computing in terms of easing business transactions without having to spend too much on additional infrastructure, manpower and even time. There mere fact that transactions in almost any form could be done online has made cloud computing a good answer to different business problems.

Most businesses will just resort to local installation of applications in their gadgets. Some would resort to simplified data transfer transactions such as email or online messaging system (chat). But oftentimes, these transactions are not enough especially when you have a business system that requires extensive interaction with a specific application. This could be easily installed in a local gadget but this could easily cause complication.

For example, a salesman is on the road trying to seal the business deal. But before everything could be agreed on, the salesman has to use certain applications. This will not be possible if the application will not work on the local gadget. But if the salesman uses an online application through cloud computing, not only will they be able to show considerable data but real time interaction with upper management.

Number One Challenge: Data Manipulation

One of the biggest concerns of businesses when they opt to migrate to cloud computing is on how they could transfer the massive data they accumulated online. Although the services available in the industry today could very well handle type and required storage capacity of data, getting them right for the first time is very difficult.

Cloud computing is not just data transferred online which could be extracted anytime. They have to go through certain processes, access management and how to properly dispose those data by requests. All of these have to be considered with optimal security in mind.

These can’t necessarily be executed at will by any businesses. They are left at the mercy of the cloud computing provider to ensure everything is according to expectation, especially security. For that reason, businesses have to make sure they work with a reputable cloud computing provider to ensure everything is according to certain processes.

Balancing and Scaling

Developers would have to make sure they are building an application, especially when launched online, could be easily management and have the capacity to hold massive loads. This is a must for business applications as massive data requests will happen. If they are not controlled, certain functions of the application will not work.

Although the server will be able to handle data requests, the application itself will not have the ability to control the data. This situation might lead to certain security concerns such as data leaks.

Businesses have to choose a provider that will give them the capability of balancing loads. Some providers even have auto-scaling function wherein the load is automatically balanced whenever the load is getting heavier due to massive requests.

{mospagebreak title=Monitoring Capabilities}

Monitoring Capabilities

The challenges for the enterprise could be easily handled if the application and the data centers with server farms could be actively monitored. The monitoring system should be consistent and should have the capability to provide monitoring 24/7 without any falter.

Any form of latency should be actively monitored. Monitoring should not only be based on the application running with the data centers. Monitoring should be actively provided for the hardware. The local environment and active CPU capability found in the data center should be considered.

Security

It goes without saying that the biggest concern any business have in cloud computing is security. Without security, the application will be highly vulnerable to different form of attacks.

From simple attack on certain application to hardware security on different data centers, these security measures have to be implemented without any flaw. A single attack could easily destroy everything. That means no matter what security measure they implement, one flaw in security could potentially destroy everything.

The key in proper implementation of security in the enterprise is consistency. It should be present at all time and should receive more than enough resources to make sure security is in place. Businesses have to check every security measure implemented in cloud computing to ensure success in their operation.
