The Four Types of Clouds Explained

In meteorology, you have cumulus, cirrus, stratus, and nimbus. In computing, you have private, public, hybrid, and community. Here's what each means:

Private cloud: The cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premise or off-premise.

Public cloud: The cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: The cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).

Community cloud: The cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on premise or off premise.

Monitoring Internal Applications with Cloud Application Perspective

With Cloud Application Perspective (CApP), Keynote can now be used to monitor internal and private applications just easily as one might monitor a public one. Since CApP is a customer installable monitoring agent, it can be easily deployed in branch offices, customer locations, and of course data centers to monitor internal private communications. Much of what the First Mile and API How To posts cover with respect to scripting and deploying measurements are equally applicable to internal applications.

An important detail when deciding to monitor internal applications is why. Well the obvious answer is that internal users are impacted by performance issues, which in turn influences their productivity and satisfaction. These are factors that a sophisticated IT operation should care about in the age of cloud computing and web applications. However, another reason is vendor selection and contract renewal. Monitoring services with Cloud Application Perspective provides a wealthy of good data that can be used to better choose among vendors, inform contract renewals, and in general keep them honest.

Here is the complete guide on Cloud Application Monitoring.

Can your customer rely on your mobile site?

We often talk about speed and optimization, but site reliability is just as important to get your customers to repeatedly visit to your mobile site and build brand loyalty. According to the Keynote Mobility Survey, 48% of smartphone users experienced a problem with loading errors and the inability to open the page.

This can be a frustrating experience for mobile users and a good reason to either not come back or visit your competitors mobile site. 

There are a few standard practices to combat the pitfalls of bad performance, and continuous monitoring & testing is the best way to find out when and where your mobile site is failing. Finding issues before your customers do and fixing them quickly is the key to scoring well in terms of website reliability. 

Who does reliability right?

Keynote keeps running measurements of mobile websites from several industries on our KeynoteMobile Performance Indices. On any given week we can see different companies at the top of the list for reliability. But if you follow the weekly indices long enough you'll see that the companies that rank best tend to be the same, suggesting a greater attention to mobile website availability. For the week ending September 9th, here's who were on top

Test Your Site on IE 9 and Measure User Experience

Few months back, Keynote announced that the Keynote Global Network was being updated with Internet Explorer 9. As a result, our real browser monitoring service, Transaction Perspective™, is now measuring the performance of Web applications and sites using Microsoft’s latest Web browser. This makes Keynote the first on-demand monitoring service built on IE 9, which is pretty cool. But what’s even cooler is the ability that IE 9 gives us to measure a new class of performance metrics we call user experience metrics.
IE is still the big kid on the block when it comes to browser usage. With the demise of IE 6 in the United States, and the rise of Firefox and Chrome, it’s clear that users are quickly leaving “old” browsers for “modern” ones like IE 9. With high performance and broad support for open Web standards, browsers like IE 9 make it easier for companies to create a rich and snappy experience for consumers. In response, 34% of the top Internet sites now use HTML 5, and the use of JavaScript continues to rise. Transaction Perspective built on IE 9 allows customers to get a more precise view of their site performance, especially those leveraging new Web standards.
Our new Live Beta preview of MyKeynote 11 with Transaction Perspective lets you see performance in very important ways Learn More

Speed and Tenacity: the Apple iPad Outage

We’ve heard a lot recently about the importance of speed and performance when it comes to online retail. The New York Times highlighted research from Microsoft claiming that 250 milliseconds—a mere eye blink—could make the difference between a repeat visitor and a lost customer. And a popular infographic touts that Amazon would stand to lose $1.6 billion in sales per year from a 1 second web page delay. Our friends at Walmart.com have also shared some awesome research linking web performance to conversion.

These statistics are welcome news for the web performance community. But sometimes they don’t apply. With Apple, a lot of rules don’t apply.

To Apple’s credit, the Apple store normally runs very quickly—averaging well less than 2 seconds for total User Experience Time and less a second for Time to First Paint. (The Apple Store is a member of the Keynote Retail Performance Index, measured with Keynote Transaction Perspective.)

Your product/service is unique. And your customers are also unique. Keynote web load testing consultants dig into web analytics to model user behavior. They consider familiarity, tenacity, interaction speed and connection speed when developing virtual user profiles. It may be unrealistic for you to understand how different levels of performance impact your various customer types across all these variables. But if you can begin to understand them, you’ll be in a better position for setting ongoing performance goals and SLAs—especially around tolerances for outliers from your averages.

Monitoring User Experience of the Cloud

In this blog, we are going to talk about metrics to build into service level agreements and learn how to track the quality of service users of SaaS and cloud applications actually experience.

Q&A With Vik Chaudhary, VP of Product Management and Corporate Development, Keynote Systems

Phil Waineright: I’m glad to have you with us because your — Keynote — is a SaaS provider itself, but you also actually work with SaaS and cloud companies who make use of your services, don’t you?

Vik Chaudhary: That’s right. In fact we do both. We started out as a cloud company and a SaaS company, well before those words were even invented, back 14 years ago. And today, we work with about 2800 different companies all over the world; SaaS companies are among them.

Phil Waineright: Right. So okay. So this part of the business is serving traditional enterprise businesses but part — a growing part I suppose of the business — is serving the cloud vendor community of one type or another.

Vik Chaudhary: As it turns out, the cloud vendor community is — especially in the SaaS world — is growing to include businesses that are using SaaS vendors very effectively. And because businesses typically care about their online performance and customer experience, they happen to look to us to help moderate the conversation between them and the SaaS providers so we can assure that performance and reliability of their applications are really top-notch.

Cloud Computing Insights

In a private network world you would have to build and pay for a lot of stuff yourself: multiple data centers, double the hardware, internet access connections on opposite sides of the building, etc. Very quickly the cost of high availability gets prohibitive, locking out all but the deepest of pockets. 

With Cloud Computing,  having access to redundant data centers is just a matter of purchasing the right performance monitoring tools and the engineering time in programming your applications and operational systems to take full advantage of on demand resources. In the end you only pay for what you use of the infrastructure, not what you might need as is the case when doing it yourself. 

Cloud Computing is not outsourcing, this implies a transfer of risk and responsibility. Cloud Computing is a powerful tool to increase performance and availability many fold while reducing costs, if it’s used correctly.
