Modern Application Performance Management (APM) solutions can be tremendously helpful in delivering end-to-end visibility into the application delivery chain: across all tiers and network sections, all the way to the end user. In previous blog posts we showed how to narrow down to vari...
Encryption is a key element of a complete security strategy. The 2013 Global Encryption Trends Study shows a steady increase in the use of encryption solutions over the past nine years. Thirty-five percent of organizations now have an encryption strategy applied consistently across the...
Do you have a PHP application running and have to deal with inconveniences like lack of scalability, complexity of debugging, and low performance? That’s bad enough! But trust me: you are not alone. I’ve been developing Spelix, a system for cave management, for more than 20 years. It ...
In Part V, we discussed processing delays caused by “slow” client and server nodes. In Part VI, we’ll discuss the Nagle algorithm, a behavior that can have a devastating impact on performance and, in many ways, appear to be a processing delay. Beyond being important for (reasonably) a...
“Vote early and vote often.” Back in the 1920s and ’30s, when neither election technology nor oversight were as effective as they are today, and the likes of Al Capone were at work gaming the system, this phrase wasn’t a joke. It was a best practice. If you want guaranteed results, wh...
Can a postmortem review help foster a curiosity for innovative possibilities to make application performance better? Blue-sky thinkers may not want to deal with the myriad of details on how to manage the events being generated operationally, but could learn something from this exercise...
The introduction of the Cloud has enabled the fast and agile data recovery process which is effectively more efficient than restoring data from physical drives as was the former practice. How does this impact Backup & Recovery, Disaster Recovery and Business Continuity initiatives? Cl...
Windows XP is living on borrowed time: Microsoft officially ended extended support for it on 8 April 2014. It was inevitable, but now many companies and organizations across the world face the unenviable task of removing XP from their organizations without disrupting regular business a...

As the number of companies adopting cloud-based solutions continues to increase, security remains top of mind for vendors, companies and their customers. Organizations of all types and sizes are opting for cloud e-signatures for many reasons including speed-to-market, agility and a low...
We’ve written before about some of the high-profile data breaches occurring in recent months – security breaches that cause some to question the safety of the cloud to store and/or process sensitive data. It seems these stories are reported with increased regularity (sometimes delayed,...
Let me ask you a question: would you say that you have implemented logging correctly for your application? Correct in the sense that it will provide you with all the insights you require to keep your business going once your users are struck by errors? And in a way that does not advers...
In many industries, cloud computing is now vital to remaining competitive. The cloud typically offers superior flexibility, scalability, accessibility, and high availability, enabling businesses to grow more agile and responsive. Regulatory compliance concerns often make banks and othe...
In 2013, the total cost of natural disasters reached $192 billion, according to recent research from Impact Forecasting, a division of reinsurance company Aon Benfield, who conducts these reports each year. In 2012, Hurricane Sandy topped 2013’s most costly natural disaster. With dam...
Lately we have seen a lot of articles discussing how easy Disaster Recovery in the cloud is but very few of those put the emphasis on talking about the basics of Disaster Recovery and educating customers on why they should be thinking about it. There are six myths that needs to be addr...
Have you ever deployed a change to production and thought “All went well – Systems are operating as expected!” but then you had to deal with users complaining that they keep running into errors? We recently moved some of our systems between two of our data centers – even moving some c...
This year like last year, XebiaLabs polled Fortune 1000 companies in banking, manufacturing, healthcare, government and IT, interviewing DevOps teams and everyone from QA to C-level suites. More than 1,000 people were asked to share their perspectives on software delivery trends. Last...
Service Level Agreements (SLAs) offered by cloud providers are too often about Specification and not Service. It should come as no surprise that vanity metrics, like Availability, are used instead of business metrics because they are simple to measure and easy to misconstrue. Metrics t...
There are two pieces of good news to come out of Heartbleed. First, we haven’t heard of any significant security breaches, which mean that the industry as a whole is getting better at fixing problems as they arise. The second is that, because Heartbleed presented every single cloud pr...
So what does real-time mean anyway? An example is, what are referred to as, “hard-real-time systems” [2], where computation must meet stringent timing constraints and one must guarantee that those computations must be completed before specified deadlines. Failure to do so can lead to i...
Learn how MedicAlert automated the functional, security, and performance testing for new APIs – enabling them to become an increasingly agile and valued provider of new healthcare information services. MedicAlert pioneered the use of medical ID products and delivers the most dependabl...
Enterprises are moving more and more applications to the cloud. Gartner predicts that the bulk of new IT spending by 2016 will be for cloud computing platforms and applications and that nearly half of large enterprises will have cloud deployments by the end of 2017.1 The far-reaching...
Setting up a deployment process on the cloud means a variety of choices. Most likely you’re prepared to make some tradeoffs. But getting a view across these potential tradeoffs can be difficult. Here are six popular deployments and advice for making the best choice for your organizatio...
We first discussed Super Bowl lessons learned around bloated web pages that brought down sites like Kia.com. On the other side, GoDaddy did a great job in reducing the page load just for the time of the Super Bowl to ensure that their site wouldn’t go down. But there is more to learn ...
For years, the benefits of moving to the cloud – including lowered costs, flexibility and faster time-to-market – have been espoused. But among IT professionals, there remains widespread reticence about migrating mission-critical applications over, due in large part to performance conc...
How often do you deploy new software? Once a month, once a week or every hour? The more often you deploy the smaller your changes will be. That’s good! Why? Because smaller changes tend to be less risky since it’s easier to keep track of what has really changed. For developers, it’s ce...
There’s been plenty written and predicted about the future of cloud and Software-as-a-Service, and it’s hard to argue with its benefits – for both organizations and users. If our cloud-based future is to come true though, we must pay closer attention to the service levels users are get...
While any load testing solution will enable you to do some sort of load testing in your Agile environment, comparatively few enable you to follow recommended best practices and overcome the challenges many teams face with load and performance testing on an Agile project. Agile teams ...
The new wonder metal, graphene, is being looked at as a building block for communications and electronic devices on the level of what the transistor was sixty years ago. Graphene is a one-atom thick, mesh-like (think hexagonal honeycomb or chicken wire), semi metal that will add more ...
So many organizations switched to third-party help desk solutions without really putting in place any performance measures or tracking mechanisms to really measure how good – or bad – the support is. Some executives got a big bonus for “thinking out of the box” and coming up with a c...

If last year underscored anything, it was the significant and far-reaching impact of breaches by trusted insiders – case in point, the Edward Snowden affair. What makes this such a critical trend for 2014 is the fact that as more and more organizations are adopting cloud strategies, th...
With the "API economy" dominating the headlines in 2013, it's no surprise that Parasoft saw a surge of interest in how to ensure API reliability, security, and performance. Here's a recap of the 13 most-accessed API Integrity resources from 2013... API Integrity: How Buggy Are Today's...
We recently completed a proof-of-concept (POC) that involved pulling data out of DynamoDB and into Redshift so that business users could analyze the data in an ad hoc manner with JasperSoft. JasperSoft and Redshift are touted as the new way to do data warehousing in the cloud and we we...
Like millions of other Americans, I learned the other night about the massive data breach at Target. The Washington Post is reporting that sensitive details on over 40 million credit and debit cards were exposed. While the information associated with the crime is still coming out, the ...
While some providers tout the evils of running agents on your system and can oft be heard shouting, "no agents here!!!", we prefer to keep an open mind at Logentries. We'd rather not dictate to our community what approach to take when collecting log data nor do we try to prescribe what...
