Cloud Computing and ROI

cloud-computing-and-roi

Cloud Computing and ROI

Most think cloud computing is about the ability to save operational costs. That may or may not be the case, depending upon your enterprise or ecommerce problem domain. Indeed, there are many dimensions to consider here, including:

  • Ongoing operational cost reduction.
  • The value of preserving capital.
  • The value of upsizing on-demand.
  • The value of downsizing on-demand.
  • The value of shifting the risk.
  • The value of agility.

Let’s explore each:

Operational Cost Reduction

We all know that cloud computing is cheap…okay, cheaper…okay, it can be cheap. Thus it’s a good idea to figure out the actual cost reductions that cloud computing can bring to your enterprise IT. The trick here is not only to figure out how much money can be saved, but how much it will cost to save that money.

Preserving Capital

It’s money in the bank which allows the business to run. The more money we have in the bank, the more we can purchase things for the core business such as inventory that can be sold, or new plant equipment that will save the company money during production. In any event, it’s good to keep as much capital as possible on hand to invest in the business, and not into infrastructure such as data centers, hardware, and software.

Upsizing On-Demand

Core to the ability to preserve capital is the ability to upsize your IT infrastructure on demand, or simply pay more operational dollars for additional computing capacity which would traditionally require a capital expenditure. Many cloud computing providers call this being elastic, or the ability to grow or contract to accommodate the business. For example, you can call upon the cloud computing provider to support an additional user and processing load through the holiday, when considering ecommerce solutions.

Downsizing On-Demand

Like upsizing on-demand, you need to consider what it will take to reduce computing capacity and dollars paid. What does it take to scale down in case you no longer need the computing resource and want to reduce costs as well? Such is the case within many ecommerce systems with capacity requirements that are seasonal.

Shifting the Risk

Another core value of cloud computing is the ability to shift the risk from your enterprise to the cloud computing provider. This concept refers to the fact that, since it’s up to the cloud provider to handle the computing processing load and you’ll pay by use, then it’s possible to reduce the risk that you’ll run out of capacity to support your customers and core business processes. The risk functionally shifts to the cloud provider who is better suited to accept that risk.

Agility

Agility means the ability to change the IT infrastructure faster to adapt to the changing needs of the business, such as market downturns, or the introduction of a key product to capture a changing market. This, of course, provides a strategic advantage and allows the business to have a better chance of long-term survival. These days many enterprises are plagued by IT infrastructures that are so poorly planned and fragile that they hurt the business by not providing the required degree of agility.

Overcoming Cloud Computing Obstacles – Cloud Computing adoption challenges

overcoming-cloud-computing-obstacles

Overcoming Cloud Computing Obstacles

How to Make the Case to Switch to the Cloud

Companies choosing the cloud computing route often have to make the case for the switch to new technology to a board or investors. The most common obstacles raised towards adoption of cloud technology are concerns around the availability of service, security and auditability of company data and performance issues around data transfer or loading speeds.

Availability of Service

The utility computing economy is currently such that competition is growing among providers. There are a few large, corporate providers of cloud services, such as Amazon and Google, as well as a large handful of small and medium players in the market. The number of companies jumping on the cloud provision bandwagon is growing very rapidly, and because of this, there is great focus on providing a reliable and stable service. Many providers will offer their clients a Service Level Agreement (SLA), stating the acceptable levels of unplanned service downtime, as well as what amount of compensation is available should the SLA be breached. Companies signing up with a cloud provider should look for an SLA offering at least 99.9% availability, but preferably 99.99%. The best way to ensure full systems available for a company’s cloud services is to engage more than one cloud provider for the provision of the same service. This way, if something should happen to the first provider, the second one will be able to pick up the slack.

Security and Auditability of Company Data

Many cloud computing providers offer data encryption as part of their service. Small and medium sized businesses, that are not accountable to regulatory bodies can probably use the standard encryption technologies provided by most utility computing services. Companies, such as small investment firms or hedge funds, will need to invest in higher security measures for storing data in the cloud. By nature, most of the cloud computing infrastructures currently available by mainstream providers are what is known as public clouds. (Armbrust, et al) This means that computer systems are purposed for general use among all customers, and no distinction is made as to which company is using what hardware. This is generally fine for the standard SME, but those requiring data audit capabilities will need what is known as a private cloud. The private cloud is a collection of computing systems that has been walled off, both physically (in a caged area of a data center) and logically, using combinations of Virtual Private Networks (VPN), firewalls and, often, private leased line data connections which are installed to directly connect a company to its cloud service provider.

Performance Issues

There is often concern around the performance of data transfer within cloud applications. However, it has been shown that, generally, once data has been transferred to the cloud, the speeds of transfer between cloud servers is then much faster than it was on local drives. This is because most current cloud computing infrastructure is far more powerful than what is normally seen in SMEs. The obstacle here is the initial transfer of data onto the cloud service. This can be overcome by loading all data on portable hard drives and shipping it to the cloud service provider for the initial load. Generally, once the initial load is complete, subsequent file transfers will be much smaller in size. Exceptions to this are the data-intensive users of elastic cloud services. For these users, hard drive transfer would currently still be the most economically viable option, but there is evidence that the cost of a private leased line may decrease in future as the cost of high-end routers decreases. (Armbrust, et al)

With a careful analysis of company IT infrastructure requirements, and an appropriate plan to minimize the risks associated with the top obstacles to adoption of cloud computing, business now have the opportunity to adopt a technology which has matured over the past decade into a feasible manner in which to provide reliable and efficient corporate computing at the fraction of the cost of a full IT hardware refresh.

Cloud Computing Trends | Cloud Adoption Analysis | Organizations

cloud-computing

We just finished the first decade of this century/millennium. The early part of this decade saw great worry about the Year 2000 problem. Much gloom and doom was predicted, but things passed off smoothly. No apocalyptic upheaval.

As we usher in the next decade, the biggest buzzword is “Cloud Computing”, a rapprochement of ASP, SaaS, SOA, Virtualization, Grid Computing, Enterprise 2.0, etc. All these buzzwords have been making the rounds over past few years. Finally, computing as a “utility” seems practical and doable. Amazon took the lead in introducing AWS (Amazon Web Services) way back in 2003. It then brought in Storage as a Service concept via S3 (Simple Shared Storage). It also introduced EC2 (Elastic Computing Cloud), where Infrastructure as a Service became viable.

I just read a nice summary of this written by M.R. Rangaswamy of the Sand Hill Group. While the momentum is on, MR says large enterprises are going to be slow adapters. Much cloud adoption is in the SMB arena where lower TCO and capex override any concern for security and scale. Older vendors like IBM will offer a hybrid model – In-house systems and cloud. This is a no-brainer, as there is a huge legacy of production systems in Fortune 1000 companies running in the premises. But “pure cloud” vendors like Google, Amazon, and SalesForce.com will push for “cloud-only” approach.

Another area of interest is data management, the volume of which has never been seen before. There is the NoSQL movement to deal with unstructured data and framework like Hadoop combined with the MapReduce algorithm is getting quick adoption for fast search.

This decade will see a big landscape change in the computing arena – from the model of computing to how we store and manage data for access and analytics.

Welcome to 2010.

Understand Cloud Computing in Simple Terms – Maximumbit Inc

cloud-computing-maximumbit-

Cloud Computing is an emerging computing technology that uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth. Cloud computing is broken down into three segments: “applications,” “platforms,” and “infrastructure.” Each segment serves a different purpose and offers different products for businesses and individuals around the world.

Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT’s existing capabilities.

In June 2009, a study conducted by Version One found that 41% of senior IT professionals actually don’t know what cloud computing is and two-thirds of senior finance professionals are confused by the concept, highlighting the young nature of the technology. In Sept 2009, an Aberdeen Group study found that disciplined companies achieved on average an 18% reduction in their IT budget from cloud computing and a 16% reduction in data center power costs.

Depending on who you are talking to, you will see different perceptions about what Cloud Computing actually is, from the simplest web-hosted solutions right through to virtualized processing environments with Web-Service initiated provisioning and decommissioning.

The main challenges for Cloud Computing before it is likely to enjoy wide-spread adoption are the following:

Persistence & Availability – The ability to continue working during outages or the ability to mitigate outages.
Privacy and National Security Concerns – The hosting of information outside of your country’s borders does concern Public Sector organizations. The US Patriot Act for example is a concern for some countries in adopting cloud services. It is thought that Country-silted Clouds may be able to address this.
Geo-Political Information Management Concerns – The Political risk a country takes on by housing information for another country.

Cloud Computing is all about:

1. SaaS (Software as a Service)


These type of cloud computing delivers a single application through the browser to thousands of customers using a multitenant architecture. On the customer side, it means no upfront investment in servers or software licensing; on the provider side, with just one app to maintain, costs are low compared to conventional hosting.

2. Utility computing


The idea is not new, but this form of cloud computing is getting new life from Amazon.com, Sun, IBM, and others who now offer storage and virtual servers that IT can access on demand. Early enterprise adopters mainly use utility computing for supplemental, non-mission-critical needs, but one day, they may replace parts of the datacenter. Other providers offer solutions that help IT create virtual datacenters from commodity servers, such as 3Tera’s AppLogic and Cohesive Flexible Technologies’ Elastic Server on Demand. Liquid Computing LiquidQ offers similar capabilities, enabling IT to stitch together memory, I/O, storage, and computational capacity as a virtualized resource pool available over the network.

3. Web services in the cloud


Closely related to SaaS, Web service providers offer APIs that enable developers to exploit functionality over the Internet, rather than delivering full-blown applications. They range from providers offering discrete business services to the full range of APIs and even conventional credit card processing services.

4. Platform as a service


Another SaaS variation, this form of cloud computing delivers development environments as a service. You build your own applications that run on the provider’s infrastructure and are delivered to your users via the Internet from the provider’s servers.

5. MSP (managed service providers)


One of the oldest forms of cloud computing, a managed service is basically an application exposed to IT rather than to end-users, such as a virus scanning service for e-mail or an application monitoring service (which Mercury, among others, provides). Managed security services delivered by Secure Works, IBM, and Verizon fall into this category, as do such cloud-based anti-spam services as Postini, recently acquired by Google. Other offerings include desktop management services, such as those offered by Center Beam or Ever dream.

6. Service commerce platforms


A hybrid of SaaS and MSP, this cloud computing service offers a service hub that users interact with. They’re most common in trading environments, such as expense management systems that allow users to order travel or secretarial services from a common platform that then coordinates the service delivery and pricing within the specifications set by the user. Think of it as an automated service bureau. Well-known examples include Rearden Commerce and Ariba.

7. Internet integration


The integration of cloud-based services is in its early days. OpSource, which mainly concerns itself with serving SaaS providers, recently introduced the OpSource Services Bus, which employs in-the-cloud integration technology from a little startup called Boomi. SaaS provider Workday recently acquired another player in this space, CapeClear, an ESB (enterprise service bus) provider that was edging toward b-to-b integration. Way ahead of its time, Grand Central — which wanted to be a universal “bus in the cloud” to connect SaaS providers and provide integrated solutions to customers — flamed out in 2005.

 

Citrix Cloud Center

C3 is designed to give cloud providers a complete set of service delivery infrastructure building blocks for hosting, managing and delivering cloud-based computing services. C3 includes a reference architecture that combines the individual capabilities of several Citrix product lines to offer a powerful, dynamic, secure and highly available service-based infrastructure ideally suited to large-scale, on-demand delivery of both IT infrastructure and application services. This architecture consists of four key components:

Platform – Powered by Citrix XenServerTM Cloud Edition:  The new XenServer Cloud Edition is a powerful virtual infrastructure solution optimized for service provider environments. It combines the cloud-proven scalability of the Xen® hypervisor which powers most of the world’s largest clouds, with all the virtualization management and dynamic workload provisioning capabilities of the full Citrix XenServer product line enabling cloud providers to host and manage any combination of Windows® and Linux environments. XenServer Cloud Edition also features an innovative consumption based pricing model to meet the needs of service providers that charge their customers based on metered resource use.

Delivery – Powered by Citrix® NetScaler’s®:  Through its rich policy-based AppExpert engine, Citrix NetScaler’s delivers cloud-based resources to users over the Web, continually optimizing user application performance and security by dynamically scaling the number of virtual machines (VMs) or servers available in response to changing workload demands and infrastructure availability. This allows cloud providers to balance workloads across large distributed cloud environments and transparently redirect traffic to alternate capacity on or off premise in the event of network failures or datacenter outages.  NetScaler’s can also dramatically reduce server requirements in large cloud centers by offloading protocol and transaction processing from backend server pools. NetScaler’s proven architecture is designed for highly scalable, multi-tenant Web applications and delivers Web services to an estimated 75 percent of all Internet users each day.

Bridge – Powered by Citrix WANScaler:  As larger enterprises begin experimenting with cloud-based services for parts of their own infrastructure and application hosting strategy, cloud providers will also need reliable and secure ways to provide a seamless bridge between hosted cloud services and premise-based enterprise services. Over time, C3 will incorporate a set of open interfaces that allow customers to easily move virtual machines and application resources into a cloud-based datacenter and back again as needed. WANScaler technology will play a critical role in this enterprise bridge by accelerating and optimizing application traffic between the cloud and the enterprise datacenter, even over long distances.

Orchestration – Powered by Citrix Workflow Studio TM: Tying it all together, Citrix Workflow Studio provides a powerful orchestration and workflow capability that allows the products in the C3 portfolio to be dynamically controlled and automated, and integrated with customer business and IT policy. Workflow Studio allows customers to control their infrastructure dynamically–integrating previously disconnected processes and products into a single powerful, orchestrated and cohesive system. This unique capability will make it easier for cloud providers to enable highly efficient burst able clouds that automatically scale resources up and down based on demand, shifting hardware resources to where they are most needed and powering them down for maximum power savings when not needed.

Today, with such cloud-based interconnection seldom in evidence, cloud computing might be more accurately described as “sky computing,” with many isolated clouds of services which IT customers must plug into individually. On the other hand, as virtualization and SOA permeate the enterprise, the idea of loosely coupled services running on an agile, scalable infrastructure should eventually make every enterprise a node in the cloud. It’s a long-running trend with a far-out horizon. But among big megatrends, cloud computing is the hardest one to argue with in the long term.

Cloud Computing: The Computer is out the Window!

cloud-computing

Debates have been heating up about Cloud Computing (CC). Biggest challenge is security and bigger bigger challenge is ‘control’ of a company’s tech assets. The only limitation so far has been internet bandwidth, reason why it took CC a while to become mainstream. Futurists such as Nicolas Negroponte saw it coming a while back and evangelized about it repeatedly in his book ‘being digital’ (a masterpiece). Entrepreneurs like Marc Andreessen saw the opportunities early and started Loud Cloud back in 1999 (now Opsware) and Amazon today generates millions in revenue because of Amazon Web Services (Amazon launched its Elastic Compute cloud (EC2) for companies to use back 2006: yes, commercially). What really triggered CC is none other than Web 2.0: all them browser-based enterprise applications! In Summary: we’ve all contributed to Cloud Computing, without realizing it. You’ve been using Cloud Computing.

Cloud Computing is fantastic for emerging economies and their speed in adopting ‘affordable’ new technology. Look what’s happening in Africa, where mobile internet and new telecom infrastructures are making it possible to leap into internet adoption. So why a computer in the first place. Computers are becoming more of a luxury item vs. a need?

Conclusion: Cloud Computing is not a trend, but a major shift in how we ’smartly’ manage technology. For those who are still in denial and resisting change, they’re already lagging and need to catch up fast, cuz that computer is out of the Window!

Great reference here on the history of CC and how far it dates back (60’s) thanks to Computer Weekly http://tinyurl.com/yj7rln3
