Classics never die



What do the winklepicker, the majestic perm and thin client computing all have in common? One answer might be that they need all had their day – quite once. Trends are often said to travel in cycles, but some would argue these ones never really went away which they’ve been plugging away within the background, waiting to be reborn once more .



Thin client computing refers to a network of machines with limited inbuilt processing power and memory. These devices work by employing a mainframe to supply central processing and storage. Traditionally, this involved a user performing at an output device, or display monitor called a dumb terminal. These had little or no computational power to try to to anything except display, send and receive text.

A dumb terminal didn't have much processing power or memory, therefore the user couldn’t save things locally. Their use was very limited and was mainly reserved for inputting data – believe it or not, they didn’t even have Minesweeper.

[

Similar to the perms of 80s footballers, the advantage of thin client computing was that it had been rugged and required infrequent and cheap maintenance. information technology degreeTerminals had no disk drive , fans, motherboards or inputs that would break down, so maintenance was relatively inexpensive.

In comparison, modern PCs – even industrial PCs – are expensive to take care of . OS vulnerabilities, constant patching, patches that break other applications and users downloading viruses are just a few of the problems . to not mention the added cost of renewing licenses for anti-virus, firewall, office suites and operating systems. albeit properly secured and administered, things can fail for a spread of reasons.

In the 1970s and 80s, thin client computing was a staple in many industries

In the 1970s and 80s, thin client computing was a staple in many industries until the 90s rolled around and brought with them house music and therefore the rise of PC networks. These had their own processing power and therefore the humble dumb terminal and mainframe became overlooked, with many predicting their obsolescence by the dawn of the millennium.



However, like many trends, thin client computing never did truly die out. Sectors from finance to government services continued to use thin clients due to their reliability, security and ease .

This brings us to using thin clients with the cloud. Improvements in thin client hardware, software, connection protocols and server technology have meant a resurgence of thin client computing during a cross section of industries.

In the past, thin clients weren't quite ready to deliver the facility needed for top performance demands, but not anymore. Mainframes and dumb terminals have now given thanks to high-performance cloud-based workstations that you simply can carry around in your pocket.

One of the most advantages of thin client computing today is that when smartphones, tablets and thin client computers are combined with the central processing power of the cloud, they allow users from multiple locations to send files to every other with ease. Or work on live documents where there’s no confusion about the newest version or revision.

Encrypted access to non-public clouds also means thin client computing can actually be safer than PCs.

Security has taken a intensify too. Encrypted access to non-public clouds also means thin client computing can actually be safer than PCs.

Furthermore, thin client computing negates a standard problem with PCs within the workplace: users plugging in infected USBs. Many thin clients don’t have USB ports for this exact reason, or their USB ports are often deactivated to guard the network.

The moral of the story is that you simply should never dismiss a technology simply because it’s obsolete, or considered to be so. The technology columnist Stewart Alsop famously stated the last mainframe would be turned off in 1996, but they’re still going strong today and Alsop was later forced to eat his words.


Similarly, the planet of commercial automation still uses many obsolete motors and inverters that meet current energy efficiency standards and may fit into your Industry 4.0 applications, if you give them an opportunity . Sometimes you've got to travel backwards to travel forwards. You never know, 2016 might be the year we start seeing footballer style perms again.



Do the metrics of a knowledge centre impact upon its agility?



IT operations managers got to understand how their data centre is performing so as to form better decisions about how and where to take a position in their IT infrastructure. Key to those right-sized investment decisions are to seem at the varied ways to live performance; here five that ought to be considered as top priorities.



How are you able to merge heuristics with data centre metrics during a way that delivers the simplest use of space and cooling power?
It wont to be that you simply would only use heuristics to spot network security traffic patterns. However, you'll now apply heuristics to infrastructure performance issues in order that you'll quickly identify and act on any potential hacks.

In order to urge better information, it’s best to possess cross-reference visibility to NetFlow metrics with differing types of KPI’s from your more conventional silos. Doing this helps you identify any contention issues also as laying the foundations for a more intelligent investment plan. This increases productivity and makes your system much more efficient.


How can heuristic-based data centre metrics help our operations?

As the modern data centre has become more and more complex, (think conversational flows, replatforming, security, mobility, cloud compatibility) heuristics has become more and more important. This technology gives us the potential to perform back-of-envelope calculations also as taking the danger out of human intervention. the top product is right , a machine-learned knowledge domain .

Is it possible to properly model costs also as operational metrics?
When it involves managing and upgrading our system, most folks need to cope with a hard and fast budget. this suggests that we are vulnerable to ‘over-provisioning’ hardware and infrastructure resources. the most explanation for this is often that we can’t properly see the complexities that come as part and parcel of a up to date data centre.


What you would like is an efficient infrastructure performance management tool. this may assist you properly calculate your capacity and make a better-informed investment decision, which suggests that you simply simply won’t overspend during a bid to stop overloading that you can’t even see.

Can financial metrics-based modelling benefit data centres?

Data centre managers can deliver core IT operational metrics to business-side managers; during a language that creates sense by continuously illustrating a sensible view into available capacity against overall efficiency, acceptable performance thresholds between running hot and wasted “headroom,” and a greater degree of granularity in terms of ROI benefits to virtualisation over maintaining legacy infrastructures.

Using financial metrics, data centre managers can deliver concise, easy to read metrics to people outside of the IT industry. This includes people like business-side managers and other stakeholders. this is often achieved through simply showing available capacity against overall efficiency also as performance thresholds. Showing return on investment makes it easier to speak your good performance to peers.

You will find below a number of the simplest metrics with which to demonstrate ROI analysis:

TB Storage Reduction: Variable Cost / GB / Month $
Server Reductions: Annual OPEX / Server $
VM Reductions: Variable Cost / VM / Month $
Applications Reduction / Year $K
Database Reductions: Variable Cost / Database / Year $
Consulting / Contractor: Reduction $K
Revenue Improvement / Year $K
Blended/Gross brokerage account 
Facilities & Power / Year $K
Ancillary OPEX reductions / Year $K
Is it possible for data centre managers to supply a holistic operational metrics solution?
One of the simplest ways to visualise performance is thru a high-fidelity streaming multi-threaded dashboard. These real-time processing dashboards provide easy to know intelligence comprised of knowledge points and their key interdependencies, which incorporates endpoint devices, physical infrastructure and visualised applications.

The best thanks to make sure that you minimise the negative impacts of a service outage is to automate your system

The best thanks to make sure that you minimise the negative impacts of a service outage is to automate your system. we might recommend integrating with an IT operations management platform like ServiceNow. This helps increase agility and responsiveness. However, none of this is often possible without good data and visualisation. so as to predict the longer term , you would like to know what’s happening within the now.IT Recruitment and therefore the munching cloud


If the IT industry marketing machine would have you ever think that I’m writing my job/skills predictions sat on a sun kissed beach accessing and tapping my prophesies into a completely secure cloud which sits during a container, flexing up and down seamlessly thanks to the stress of myriad’s of other mystic meg jobs/skills pundits across the world . Somewhere bots are automatically creating storage /admin space only for my prophesies and infrequently a person's looks at one pane of a glass, checks everything’s fine and dandy then lets out an extended self satisfied yawn. 




My favourite saying at the instant is ‘cloud is munching everything ahead of it’ and that’s true. the large corporate capitalist machine likes to economize – to be quite frank if expensive / complex enterprise grade infrastructure can sit within the cloud more cheaply, efficiently and reduce CAPEX, then the CEO and therefore the board are going to be game on. Yet, of course, not everything can or should sit within the cloud – certain industries / sectors cannot have ‘stuff’ sat during a cloud. So think hybrid. 



We are seeing traditional IT services players morphing into Cloud / Managed Services providers.technology credit union This sector is buoyant, they're busy transitioning new clients of all sizes onto their cloud / platform. So if you think that it through the necessity for on premise IT teams is being reduced – yes the IT industry marketing machine will have you ever believe that cloud releases internal IT to focus and solve the larger core problems with the business; but don’t believe the hype, the truth is that it results in lower on premise staff numbers. 



Internal Infrastructure Support Engineers are moving to Cloud / Managed Services providers, And Cloud / Managed Service providers are needing staff to woo, win and technical prove why to maneuver to the cloud; thus more sales / presales solutions architects are needed. 

Cloud / Managed Service providers are realising that winning new business is that the easier a part of the equation; the larger part being retaining business, thus they're requiring more engagement managers, client account managers, project managers and repair delivery managers.

Big reduction in numbers of road warrior IT consultants plumbing in new technologies into on premise clients, e.g. why plumb during a new tech once you can purchase it in from a cloud vendor? there's also a discount in on premise legacy old fashioned storage roles needed, but conversely old fashioned storage contract rates may rise.


why plumb during a new tech once you can purchase it in from a cloud vendor?


In house desktop support roles are being vastly reduced, although we are seeing a transition of that role into a VIP support role – someone’s need to be available 24/7/365 if the CEO can’t access the cloud from their iPad right? 

Corporate IT staff numbers are being reduced. Those remaining are getting highly skilled all rounders, e.g. infrastructure, storage, virtualisation, networking, accessibility, security, etc – they need to be ready to cover all the bases.

There has been an enormous rise in Cloud Solution Architects, both in commission providers and on the client side. Someone’s need to design these things right? Then we’ve had a surge of Cloud Platform Architects too – big platform providers especially are the winners here; think AWS, Azure and possibly Google.

Cloud Security – there's an enormous demand here, so it’s a no brainer that there's a requirement for cloud security professionals. Ditto with DevOps – there's a requirement for the suite of infrastructure skills, and developer languages understanding, in order that new and old stuff can just simply be built / add the cloud.


I’m expecting to ascertain a rise with regard to Cloud Apps Architects – a task where old legacy applications are ‘stripped’/coded and just to try to made to figure within the cloud. an equivalent for Cloud API Architects – roles where applications/infrastructure is made in order that 3rd parties can access and buy a third party ‘cloud machine’ to ‘crunch data’, paid per cycle/call/’crunch’. this is often Big opportunity for those with the talents to execute.

Big Data / Analytics / Digital – this is often getting to be all about how the company uses its internal / social media data. Big opportunity. Companies need people to understand the way to build apps/infrastructure to message me on Twitter when I’ll get the drone delivery of that product i assumed about 5 mins ago right? 

we’re moving towards Networking / Wireless everything

And last , we’re moving towards Networking / Wireless everything – everything sitting on a network, always on, accessible from anywhere, which will bring an entire realm of recruitment challenges in itself.




IaaS, the infrastructure IT utility?



When a business today opens an electricity bill it sees the quantity of electricity used over the billing period and therefore the cost per kW-hr . What the business doesn’t see may be a separate flat rate allocated per appliance and to the varied pieces of equipment that are deployed within the office. Imagine paying a flat rate for the electricity to power your air con , but only using it heavily for two months a year; commercially it doesn’t add up . Yet we are willing to simply accept the flat rate model and therefore the complexities that accompany it once we buy and deploy cloud IaaS.


Is the current cloud infrastructure (IaaS) market, delivering a simple to use, consumer friendly service, almost like common utilities? Or should we be watching the advantages of an alternate commercial model, utility computing, which differs from the widely used cloud IaaS model.

When comparing IT infrastructure to a utility model of delivering a service it's important to define what we mean. Standard utilities like electricity and gas are delivered during a model where we, the buyer , only buy the particular amount we use. Generally, this is often considered to be the fairest thanks to buy utilities, also as other goods and services like food and commodities. All associated costs for the service, like production and delivery, are included within the amount we pay at the top of the billing cycle. The key to the success of the commercial model is there's one unit of measurement that permits the service provider to live , and charge for the quantity of resource that we've consumed.

the single unit of measurement is what makes the utility sales model successful

This model essentially removes the buyer from any of the responsibilities and financial investment into the availability , production and maintenance of the utility. the buyer is merely concerned about the cost , the quantity of resource used, and therefore the reliability of the supplier. With regards to changing supplier, all suppliers use an equivalent unit of measurement, and are therefore easily comparable. The complexities of managing supply and demand are faraway from the buyer and therefore the buying process is simplified to form the resource easy to use.

Let’s check out how this model translates into the planet of IT infrastructure and therefore the cloud IaaS market.

Traditionally organisations/ the buyer owned and invested within the technology and other people to deliver their IT. The organisation took on the responsibility of managing supply and demand, in order that they could deliver data and applications to the business. They also, inadvertently, took on headaches like keeping pace with changing technologies, recruiting and skilling specialist staff, scaling to satisfy demand, financing ad-hoc capital investment and building specialist facilities, the list goes on.


This is not an easy model for the buyer to know , and thus control. As a consequence, costs and delivery standards were, and still are, wildly different between organisations. 

The cloud era has caused IaaS and more of a utility aspect to infrastructure delivery. Cloud Service Providers (CSPs) are specialised and therefore the consumer pays on an opex basis, no ownership of assets and no responsibility for supply and demand. However, it's not common practise to buy IaaS as a real utility, or in other words only buy the resources that are used.

if you deploy a 100 IaaS instances and most of them are over provisioned for the workloads they support, then you're wasting a substantial amount of cash 

Most CSPs sell their cloud IaaS instances at a flat rate counting on the quantity of resources (CPU, storage etc) allocated. It doesn’t matter how well utilised the instance is over the billing period the customer pays the complete amount. Therefore, if you deploy a 100 IaaS instances and most of them are over provisioned for the workloads they support, then you're wasting a substantial amount of cash . For context, we see much more over-provisioned servers, than we do under-provisioned.

The other problem is variation in sizing (resources allocated) and flat rate pricing models for the IaaS cloud instances. Because each CSP’s rates and instance sizes differ, it's an excessively time consuming and sophisticated task to figure out who is offering value for money, then to forecast your future spend.

The cloud model has changed infrastructure delivery for the higher , however it's still not delivered during a consumer or business friendly model. What both the normal investment ownership and cloud IaaS models have in common is that billing units are fixed logical containers of resource. The logical containers have just progressed from physical server, to virtual server, to cloud instance. If we would like to be more efficient with infrastructure usage and IT spend, the industry must look to our common utilities for inspiration.

to be more efficient with infrastructure usage and IT spend, the industry must look to our common utilities for inspiration

For a utility computing model to be effective within the IaaS space there must be a standard unit of infrastructure measurement. 6fusion’s Workload Allocation Cube (WAC) may be a patented algorithm wont to formulate one unit of IT measurement, that mixes the 6 compute resource metric readings together. thousand WACs is adequate to one kWAC hr, almost like gas and electricity utilitiesThis unit of IT measurement is already in use to facilitate trade on a utility computing spot exchange called the Universal Compute Xchange (UCX). The exchange features a number of vetted CSPs selling their IaaS products through their online trading platform. the simplest way for patrons to shop for via the exchange is to interact a registered broker. 

The broker role may be a relatively new one in IT but not uncommon in other industries. The broker are going to be a member of the exchange and has access to raised pricing than non-members. Their role is to facilitate trade between the buyers and seller. However, as this is often IT, a buyer may have specific needs for his or her workloads, therefore the broker will got to understand the wants and buy units with all the required assurances in situ . the wants organisations currently have like performance, security, compliance and repair levels will still got to be addressed.


What the utility computing marketplace gives the customer is pricing transparency and usage based billing, so finance and business stakeholders can see where their IT spend goes . the straightforward commercial model also enables benchmarking and forecasting of future consumption and spend. This model seems superior to the currently more popular flat rate per IaaS instance, where the worth is calculated on the resources allocated. Benchmarking and forecasting future deployments and spend is inherently harder within the flat rate model.

If the longer term of IT infrastructure is to be treated as a utility and a commodity that's on tap to drive innovation and customer engagement, then consumers must demand a more commercially savvy charging model.information technology degrees It’s time to think about utility computing and therefore the commercial benefits it can bring.
