INTRODUCTION TO CLOUD COMPUTINGSo you have heard about the cloud. In fact you may even be using thecloud in your business. But do you really understand what the cloud is?Furthermore do you realise the business opportunities it could present to

your organisation and where to take this next?

At WestconGroup Southern Africa we have undertaken to give you asnapshot of the cloud, the business opportunities it presents to yourcompany and a quick guide on what it really means to be “in” the cloud.

So what is the cloud?

There are so many denitions on what “cloud computing” is. But we are going to simplify it even further.

The cloud is a metaphor for the Internet and transacting over the Internet. The cloud is not limited by hardware,“cloud computing” means that you store, access, transact over and work in/over the Internet.

To understand what the cloud is you need to know what it is not.• The cloud is not your hard drive – that is considered local or physical infrastructure

• The cloud is not your company network – that is still your internal LAN or WAN

• The cloud is not just the Internet – the Internet as we now know it is not just a web page lled world

• The cloud is not your data centre – again that is local or physical infrastructure

But then even though IT created this notion of cloud computing they took it further and created even moreclouds. No these aren’t cumulus, stratus or cirrus. They are instead the public cloud, the hybrid cloud and theprivate cloud.

Lets look at a denition of these now to create context – but know we will unpack their role in your businessa little later.

Public Cloud - A public cloud is basedon a standard cloud computing model,where a service provider (think Googleor Amazon) makes resources, such asapplications and storage, available tothe general public over the Internet.Public cloud services may be free oroffered on a pay-per-usage model. *

Private Cloud  - Private cloud (alsocalled internal cloud) is a marketingterm for an enterprise computingarchitecture that’s protected by arewall. Promotion of the private cloudmodel is designed to appeal to anorganisation that wants more controlover their data than they can get byusing a third-party hosted service.

Hybrid Cloud  - A hybrid cloud isa cloud computing environment inwhich an organisation provides andmanages some resources in-houseand has others provided externally.It marries the best of the private andthe public cloud and gives the user theability to still critical business processes(data) onsite.

TECHNOLOGYEVOLUTIONMainframeMaking it Real - Technology Evolution Time Line

The Internet, was designed in 1974, though it did notopen up until the 1980s.

According to “Banking and Finance on the Internet,”edited by Mary J. Cronin, online banking was rstintroduced in the early 1980s in New York. Four majorbanks - Citibank, Chase Manhattan, Chemical andManufacturers Hanover - offered home banking services.

NETWORK FILE SYSTEM:The le system that broughtus to the age of networkstorage. No longer would

your data be hostage to thecomputer in which it wascreated ‘ or to backup tape.

THE BROWSER:It made the Webwork for the restof us and became

publicly available.

WINDOWS 95:32-bit pre-emptive multitasking madepossible everything that has come alongfor the desktop since ‘ including thegraphical Internet and Mac OS X.

Broadcast.com becomes oneof the world’s rst online radio stations.Amazon.com began as an onlinebookstore and has gone on to formone of the greatest ecommerce sites theinternet has ever seen.

WORLD WIDE WEB:

Invented by Tim Berners-Lee,it would soon change theway governments, businessand people operate.

OUTLOOK:

Outlook.com is a free webbasedemail service run by Microsoft. Oneof the world’s rst webmail services,it was founded in as Hotmail.

GOOGLE:We’d call it the portal to the Web, except portals

aren’t this easy to use. The search bar is rapidlybecoming the sippy cup of culture ‘ with more thanpartial thanks to Wikipedia, Google’s query shortstop.

BROADBAND:Cable and Digital Subscriber Lines

start to make an appearancein homes, and telecommutingbecomes a real option.

E-MAIL:

Electronic mail goes back tothe 1960s, but -it really startedtaking off with Web use. By 1997,the volume of business e-mailsurpassed that of regular mail.

STAGES OFTECHNOLOGYEVOLUTIONIn order to see where we are going we needto understand where we have been. Where didtech start?

With the mainframe, we then moved to smallermainframes or servers. After this we took a giant leapwith the notion / concept of virtualisation – were wesaid that by making use of software we could makeone server / mainframe believe it was many. So ITshrank and paved the way for mobility to be born.Suddenly we weren’t strapped to our desks and we

could move about. In this era the Internet was bornand it started shaping how we did things. Ok so wemissed a few momentous steps in this – but we don’twant to give you a history of computing in its entiretybut rather a quick view of the cloud.

So the Internet, which is in simple terms is the motherof Cloud Computing, came the birth of this “era” weare now nin. But we aren’t just here – we are star tingto dip our toes in a new world called the Internetof Things (IoT) or machine-tomachine computing. Inthis world you can use your phone to talk to yourtoaster over the cloud. It is real and it is here.

What’s next? The guys with the big brains aresuggesting that the next phases of IT, of whichtraces are emerging, are Autonomic Computingand Articial Intelligence. But that’s ahead of us. Letsfocus on where we are … In the cloud.

* Autonomic computing is a self-managing computing model named after, and patterned on, the humanbody’s autonomic nervous system.

CLOUD COMPUTINGAND YOUSo do you use the cloud? Most people’s rst reactionis no. But lets ask you another question… Do youmake use of Internet Banking or do you use Dropbox?

Yes? Then you are in the cloud. So lets use OnlineBanking as an example to explain the evolutionof cloud computing and the progression peopletake to getting to making use of the cloud as a defacto standard in how they prefer to transact withservice providers.

The Backdrop: Online Banking

When last did you venture to your bank or a branch?

Not very often do you. It is almost a forgotten erawhere large buildings housed row upon row oftellers, who would greet you by your rst name andstamp your little leather bound savings booklet withevery transaction. Today instead of reaching for yourkeys to make a nancial transaction, do you notreach for your keyboard or your phone?

This behaviour is not dissimilar to what cloudcomputing has done for general business. Wouldyou prefer to hop in your car to drive to a physicalenvironment to have a meeting, collect data orinformation, full a simple transaction – orwould you prefer doing it from your desk.

The cloud gives people back time. It encouragesproductivity, speed of deliver and customer serviceefciencies that have never before been seen. Onlinebanking stripped away the physical layers with whichpeople were comfortable and gave them options. Itwasn’t an either or – but through its progression andits maturity people have become comfortable with itand now to a large extent prefer it.

Take this a step further and put it into an enterprisecontext and cloud computing is the delivery ofcomputing resources as a service. What resources?Software, platforms, infrastructure, storage,databases, security and even backend resourceswhich are then all delivered via a model called “as-a-Service” – we will further break down the “as-a-Service” offerings we see today a little later.

WHERE DOES THE CLOUD TOUCH YOUAND WHERE DO YOU TOUCH THE CLOUD?

CLOUD

“Cloud computing is often far more secure than traditionalcomputing, because companies like Google and Amazoncan attract and retain cyber-security personnel of a higher

HOW DO I DEPLOY

TO THE CLOUD?Cloud deployment refers to the enablement of SaaS(software as a service), PaaS (platform as a service) orIaaS (infrastructure as a service) solutions that may beaccessed on demand by your business.

The beauty of the cloud is that you can cherry pickwhat you want to live in the cloud and dictate whatyou put there at any given point.

Where you need to identify a couple of factors:• What is my organisational appetite for the cloud?

• Do I really need my own cloud?

• Does my service provider have the right securitypolicies in place?

• What do I need to keep internal and what can Imove quickly to the cloud?

• Can my staff and customers benet from thecloud?

• Will the cloud save me money in the short andlong term?

• Do I have the skills to migrate the cloud?

• Do I have the right partners and vendors in placeto help me get to the cloud?

• Are local cloud providers ready?

YOUR BUSINESSAND CLOUDCOMPUTINGSo lets summarise. Cloud computing is a delivery ofa host of services and technologies via the Internet.It refers to things being hosted off site, in the cloudor both, as opposed to things being only housedlocally or onsite. It doesn’t require bricks and mortarbut rather a collection of technology end points ordevices that come together to deliver services toyour teams, your customers or consumers.

The beauty of the cloud is that it provides options –there is no this or that – there is always the option of

both or many.

The opportunity

With the cloud businesses can transformoperations, cut costs and increase efciencies andproductivity. How?

• Making use of the cloud to access software asopposed to installing suites on each device. Thiswill help you alleviate the pressures of managinglicensing requirements, streamline costs and freeup valuable IT resources.

• For storage where you can now put your data ina secure environment in the cloud and then offerremote access to all work related data.

• Mobility, to help create a mobile environment(the mobile cloud) that enables your employeesto engage and interact with your businessanywhere and on any device. As well as a means

to let your customers engage with nyour servicesor products within a mobile environment.

What does the cloud do for IT and you?

• Creates efciencies within the IT departmentby leveraging offsite resources and minimisingthe need for additional internal staff to supportonsite systems

• Allows IT to roll out applications and systemsmore efciently, provisioning solutions on the y

• Makes use of offsite teams to supportapplications such as email, productivity suitesand even business systems

• Customised platforms can now afford businessesthe ability to roll out mobility solutions for eldworkers and eld sales teams

• Offers a single view of IT administrative tasks

• Reduces the load on your infrastructure and

conversely the load on your IT teams

• Standardisation of business systems, solutionsand user proles

SHOULD THE CLOUDFORM PART OF YOURBUSINESS STRATEGY?

When we looked at launching a cloud

programme for our reseller partners in

2014 we realised that there are large

gaps in the industry with regards towhat the cloud really is, what it can do

for business, as well as the existence

of a large disconnect between theperceived and real values the cloudcan bring to business.

I’ve probably said it more times than

I should have over the last two years,but cloud computing is not going

anywhere, so it’s about time we –

and you – get comfortable with this

massively transformative technology.

According to Gartner, “The use of

cloud computing is growing, andby 2016 this growth will increase tobecome the bulk of new IT spend.

…2016 will be a dening year for cloud

as private cloud begins to give way to

hybrid cloud, and nearly half of largeenterprises will have hybrid cloud

deployments by the end of 2017.”

Why now? IT is sitting at a precipice.We have two camps of businesses.

Those that have made massive

infrastructure investments and who

are now at a point where they need

to decide whether or not theyshould rip and replace or shift to the

cloud. The other camps are the new

By Leane Hannigan, Cloud Solutions Director at

WestconGroup Southern Africa

businesses, organisations that are

in a unique position where they can

leapfrog straight into the cloud. Many

of these are termed “born in the cloudcompanies”.

While Gartner’s predictions for thisyear are seemingly optimistic thetrend cited by infoworld.com, is that

companies will start migrating large

scale applications into the cloud as

well as build new “digital and mobilerst” applications. The natural home of

these is the cloud.

So what cloud should you select?There are three popular models. The

private cloud which you own and you

host on premises. The public cloud,where you rent or hire space from apublic cloud provider - think Microsoft,

Amazon or even Dropbox. And

then what is proving to be the most

successful and popular model, thehybrid cloud, where you marry your

private cloud with a public cloud and

ensure you have workload mobility

between these two environments.

The real benet of the hybrid cloud

is that it delivers on the cost savings

promise of the cloud as well as the

scalability and exibility that IT shops

crave. In fact, again according to

Gartner, half of large enterprises will

have hybrid cloud deployments by the

end of 2017. These ndings are consistent

with analyst rm IDC’s predictions that

spending on cloud software will exceed$112.8 billion by 2019.

In South Africa, I still believe that thereare a large number of businesses thatdo not fully understand the benets

available to them from adopting cloud.

Our own ndings from the surveys

conducted at out Cloud AccelerationProgramme (CAP) ofcially launched

last year, highlighted that many of our

resellers still have a massive thirst for

knowledge around cloud. And I don’t just mean what it is, or how it works;

what they want to know is what cloud

can do for them.

As an industry, and in our position

as a distributor of IT products and

services we believe that it is our

role to help customers unravel thespaghetti messaging the industry has

made around the cloud, and clarify

to business, the true value of cloud

computing.

WHICH CLOUD WILLWORK FOR YOU?Public Cloud vs. Private CloudIf we take a look at the denitions previouslyprovided private cloud implies it is your cloud, yoursystems and you dictate how people engage withthese, whereas public suggests it is another ’s systemson which you host your solutions and access thementirely via the Internet.

Both have their benets and both have theirdisadvantages.

Accessibility

Public clouds allow you to replicate data to many

applications with a single login through the Internet.It is ideal for multi-branch organisations that haveofces around the globe. Limitations creep in whenthere is bandwidth constraints.

Security

Public clouds are publically accessible which doesmean that customers who have client sensitive datathey need to store in the cloud are today a littlereticent to put this all in the cloud. While there aresecurity solutions that rewall your data – it’s a risk

prole that many are still navigating.

Here the private cloud comes into play, especiallyfor nancial services companies and eventelecommunications organisations that want tosafeguard their customer data. Businesses elect theprivate cloud over the public cloud as a means to getaround potential security concerns.

Selecting either a Public or Private Cloud

The reality is that the public cloud is much easier todeploy. You purchase the service and you roll it outamongst your users, immediately reducing the needto adjust your current infrastructure investments inorder to scale into the cloud. With it you pay forwhat you use. It is very attractive to small to medium

businesses who want to move away from needing ITresources to “support” them.

Conversely the private cloud’s dedicated hardwareand bandwidth resources make it an attractive optionfor many large enterprises. Yes it provides resourceson demand, but it also preserves your currentinfrastructure investment as well as enables you todictate your security policies, offers dependableavailability and a high level of control.

The new darling – The Hybrid CloudBoth private and public clouds can be advantageousto your business so why chose? You don’t have to.With the hybrid cloud you can make use of the bestof both worlds, retain control, dictate security andoutsource and insource as and when you need to.

Remember a hybrid cloud is an infrastructure thatincludes links between one cloud managed by you(private cloud) and at least one third party cloud(public cloud). In the hybrid cloud your “clouds” do

not have to meet, but instead offer different servicesto different parts of your organisation based on yourcompany’s appetite for both.

It is scalable, fexible and manageable – it remains in your control.

MYTHBUSTERS– THE TRUTHOF CLOUD

COMPUTINGWith anything that is new and that is misunderstoodcome a number of myths and the cloud is noexception. Cloud computing is itself shrouded inmyths and misperceptions – the very things that areslowing its adoption and impeding innovation in theindustry. So here are a few myths that we would liketo bust on your behalf.

Myth 1: My data is not secure with the cloud...

Some clouds are not and it’s important to check withthe cloud provider that you are engaging with. Butas a general rule anyone who is putting togethera cloud based datacentre is ensuring they havethe security solutions in place to ensure your datais encrypted and secure. Companies make use ofa defence-in-depth approach to provide physical,logical, and data layers of security features andoperational best practices.

Myth 2: I am not allowed to store my data outsidethe borders of South Africa...

Thanks to our friends at Microsoft for this answer.There is no law in South Africa that prohibits youfrom storing your data outside the borders of SouthAfrica. The PoPI Act refers to the Protection ofPersonal Information and, as citizens of South Africa,how we need to treat information. Financial data andrecords can be stored outside South Africa providedyou meet the requirements of SARS.

Myth 3: I need to be connected to the Internetall the time...

Not always and not with all applications. Lets lookat Ofce 365 as an example here. You can work onyour documents, emails and content in an ofinestate and when you are ready you can connect tothe Internet and synchronise your data and emails.

You do not have to be connected to be productive.This is the same for applications such as Amazon,Google Drive and even Dropbox.

Myth 4: There is not enough bandwidth inSouth Africa...

We hear this one all the time. Yes some companieshave small lines, but its not because the bandwidthisn’t available it is more a case that they aren’t onthe right package, or don’t know what is availableto them. What’s more, there has been signicant

investment into bre bandwidth solutions, givingSouth Africa access to the Internet and improvedbandwidth speed. This has driven lower pricing.Currently cost-effective bre communication to yourofce is common and soon you will see bre in yourhome.

Myth 5: It’s cheaper to do IT myself...

No IT services aren’t traditionally cheap, but thecloud has changed that. Remember as an SMEcustomer as an example there are a number of coststo factor in, for example the costs of your server andlicensing at the time of deployment, versus over athree-year period. What was the true cost of runningthis yourself? For instance if email is down how muchdid this cost your organisation? Have you consideredthese factors when evaluating how much cheapera solution such as Ofce 365 is for your business.The cloud takes the pain out of maintaining, running,refreshing and even hosting your IT solutions –ultimately making the costs much cheaper.
