Running highly available Microsoft workloads in AWS

July 19, 2019 by Jason Aw Leave a Comment

Running Highly Available Microsoft Workloads In AWS

I remember when Storage Area Networks (SAN) were introduced in the late 1990s as a way to provide very fast access to storage from all connected servers.  SANs became the storage technology to deliver clustered server solutions for high availability. It enabled a common shared database to be accessed by a failover server in the event a primary server failed.

SANs, although fast, were expensive and difficult to set up and manage.  Other solutions that used high-speed efficient replication technology to synchronize data between two servers became a popular lower-cost alternative to provide high availability.

The Challenge

Fast forward 20 years, SANs are simpler and less expensive to set up and manage and are a very common solution today when failover from one server to another is required to maintain application availability Service Level Agreements (SLA).  Now many companies are looking to move workloads to the cloud to provide lower cost and higher availability.  Are you planning to move a workload to the cloud?

There is one thing many people don’t realize until they do the research. A shared storage SAN infrastructure is not available in the cloud.  Cloud providers talk availability of 99.9% for the infrastructure, power, cooling, storage, network, compute – but not a word on application availability!

If you require highly available applications and access to data in the cloud, you need to add a software-based high availability solution to your technology stack.

The Solution

Amazon Web Services (AWS) recognizes that additional solutions for high availability are required and has a special team focused on Microsoft workloads running in AWS.  On July 11, AWS awarded SIOS their Microsoft Workloads Competency status within the AWS Partner Network.  This differentiates SIOS as a partner that provides demonstrated technical proficiency and proven customer success with specific tools to monitor and recover applications and data with minimum operational impact, providing high availability for Microsoft workloads, and delivering solutions seamlessly on AWS.

Take a few minutes to review the SIOS solution and AWS Quickstart on the AWS Marketplace.

Here’s who’s talking about SIOS and its new AWS Microsoft Workloads Competency status:

Free SQL Server 2008 Security Updates!?!

May 14, 2019 by Jason Aw Leave a Comment

Free SQL Server 2008 Security Updates!?!

FREE! Did I get your attention? Free what though…?

Everyone uses the word “free” as a way to get our attention. But typically the free offering is pretty much worthless. That, or the cost is simply being wrapped into whatever is being sold. Rarely is something of actual VALUE given for free. But THIS “free” offer has real value, especially if you are still running SQL Server 2008/2008 R2. Microsoft is offering FREE security updates for SQL Server 2008 when it reaches end-of-support (EOS) on July 9, 2019.

From all accounts, there is a massive install base of SQL Server 2008. Some have indicated more than half of all SQL Server deployments are 2008. This would mean a lot of very concerned DBAs who will be losing security updates in a few months. So what? Once a vulnerability is identified, all the bad guys that want to steal your critical data will exploit it. Without security updates, these systems will be wide open for them to help themselves.

Microsoft is Offering 3 Years of Security Updates to Move SQL Server to Azure

So, what’s free that will actually help? Microsoft is offering 3 years of security updates at no cost IF you move those SQL workloads to their Azure cloud. Sure, there is a cost to hosting these systems in Azure, but that cost will be offset by the reduced cost of hosting and managing them on-premises and all the other benefits cloud offers. And let’s face it, you’ve probably been considering moving to the cloud anyway, and this may be just the right opportunity to make that leap.

Something to consider when planning your move to Azure is your clustering solution. Like most SQL Server deployments, you probably have your systems protected against downtime using a shared-storage clustering solution, like Windows Server Failover Clusters (WSFC), or they are running in VMs protected by VMware HA. The issue that you will face is that the shared-storage subsystem WSFC requires isn’t available in Azure and there is no hypervisor failover option like VMware HA either.

SIOS Provides High Availability for SQL Server 2008 in Azure

That’s where SIOS can help. SIOS solutions alleviate the need for shared storage. We provide block-level data replication between two nodes that happens transparently to Windows Server Failover Clusters. Thereby, allowing you to continue to provide high availability for your SQL Server 2008 instance by deploying a SQL Server SANless Failover Cluster Instance (FCI).

Together, SIOS and Microsoft enable you to confidently deploy your SQL Server instances in Azure, maintaining availability and security SLAs. Speaking of free, check out our free offer to assist you with maintaining support for SQL Server 2008 by moving it to Microsoft Azure in a highly-available cluster configuration. We will assist you in designing, deploying, configuring, and validating your SQL Server environments in Microsoft Azure.

Put an End to Trial and Error with Machine Learning Analytics

June 6, 2017 by Margaret Hoagland 2 Comments

When end-users report slow performance in business-critical applications, IT teams everything to fix the problem as quickly as possible. In virtual environments, where the root causes of problems are rarely straightforward, they may spend days trying and testing multiple different solutions. Troubleshooting this way creates a huge drain on IT time and resources – and even occasionally, morale. IT teams want to be innovators who add value to their business operations with new technology that automate manual tasks, increase end user productivity, streamline costs and respond to business needs quickly and flexibly. Unfortunately, without the insights and automation that machine learning analytics provides, IT departments are wasting more and more time and resources on low-value problem-solving.

ViSIOS iQ Machine Learning Analytics Eliminates Trial-and-Error Frustrationrtual Infrastructures are Too Complex
for One-Dimensional Approaches

What is causing this problem-solving quagmire? IT is running more business critical applications in complex, dynamic virtual infrastructures where traditional diagnostic and monitoring tools cannot identify root causes of application performance issues or provide specific steps to solve them. IT teams are still looking at their virtual infrastructures in individual operational silos – compute, application, storage, and network. They are using multiple tools to gather information about each silo and then piecing the results together manually to devise a theory about the root cause and a strategy for resolution.

Threshold-based Tools and Old-School Approaches

In a recent survey SIOS conducted, 78 percent of respondents are using multiple tools to identify the cause of application performance issues in VMware. Only 20 percent of respondents said the strategies they are using to resolve these issues is completely accurate the first time.

Legacy monitoring tools use threshold-based technology that was originally developed for physical server environments. They help you keep physical components operating within specific parameters, such as CPU utilization, storage latency, and network latency. You manually set the parameter thresholds for every metric you want to monitor in every silo and these tools will alert you every time a threshold is exceeded – often hundreds of times for a single incident.

More Data is Not More Information

In virtual environments, virtual resources share the physical host, storage, and network resources. These components work together in complex interrelationships that often mask the root causes of performance issues. IT pros responsible for each silo have to decipher hundreds of alerts and pinpoint what matters using their subjective opinions and good old trial and error.

Fortunately, new machine learning analytics solutions like SIOS iQ use deep learning techniques to look across the silos, factor in the interrelationships of virtual resources, and identify the root causes of application performance issues. They use predictive analytics technology to identify the issues that will cause performance issues in the future so you can avoid them. They provide a degree of automation, precision, and accuracy that humans with threshold-based tools cannot approximate.

Machine Learning Analytics Eliminates Trial and Error

Machine learning analytics tools tell you how to resolve the issues. You don’t need to weed through hundreds of alerts or compare dashboards filled with charts to diagnose the problem. You get the info you need without the expertise of a data scientist. With machine learning analytics, there is no need for data selection, modeling, preparation, extraction or configuration is necessary. SIOS iQ tells IT which infrastructure anomalies are important and which are minor so they can prioritize their valuable time.

With new and advanced machine learning and deep learning tools, IT teams can move from a reactive to proactive state. That means you can spend more time innovating and less time on trial-and-error.

Announcing AWS Quick Start Deployment Templates for SIOS SQL Failover Cluster

May 15, 2017 by sios2017 Leave a Comment

AWS Quick Start Templates Deploy SQL High-Availability Failover Cluster in the Cloud

Many businesses are struggling to deploy a high-availability failover cluster for SQL Server and other important applications in the cloud. This is because you need shared storage to create a failover cluster. Shared storage is not available or practical in most public clouds. As a result, Many IT teams kept SQL on-premises. Their experts in IT network, storage, and server would take months to plan, order, install, and configure physical environments for HA failover clustering. Finally, they would spend spent thousands of dollars upgrading to SQL Server Enterprise edition to gain advanced clustering capabilities.

SANless Failover Clustering Enables Cost-Efficient SQL High Availability Protection in the Cloud

Today, SIOS DataKeeper Cluster Edition is the first HA/DR solution to combine fully automated, application-centric clustering and efficient data replication. By integrating seamlessly into Windows Server Failover Clustering (WSFC), it enables a WSFC to work in a cloud where shared storage is not possible. SIOS DataKeeper works by synchronizing local storage in real time using highly efficient block-level replication. In this way, creates a SANless cluster to protect your Windows applications in the cloud.

Part 2- AI: It’s All About the Data: The Shift from Computer Science to Data Science

April 14, 2017 by sios2017 Leave a Comment

This is the second post in a two-part series. Part One is available here. We are highlighting the shifting roles of IT with the emergence of machine learning based IT analytics tools.

Machine Learning Provides the Answers

The newest data science approach to managing and optimizing virtual infrastructures applies the AI discipline of machine learning (ML).

Rather than monitoring individual components in the traditional computer science way, ML tools analyze the behavior of interrelated components. They track the normal patterns of these complex behaviors as they change over time. Machine learning-based analytics tools automatically identify the root causes of performance issues and recommend the steps needed to fix them.

This shift to a data-centric, behavior-based approach has major implications that significantly empower IT professionals. IT pros will always need domain expertise in computer science. But what analytical skills will IT need to become effective in this new AI-driven world?

Unlike earlier analytics tools were general purpose or provided relatively low-level primitives or APIs, leaving IT to determine how to apply them for specific purposes. Early tools were largely impractical because they had limited applicability. Moreover, IT pros using them had to have a deep analytical background. New tools are much different. They allow IT pros to leapfrog ahead -to use advanced data science approaches without specialized training. Artificial IntelligenceThey automatically deliver fast, accurate solutions to complex problems like root cause analysis, rightsizing, or capacity planning.

First, IT will shift their emphasis from diagnosing problems to avoiding them in the first place. Next, freed of the need to over-provision to ensure performance and reliability, they will look for ways to optimize efficiency. Finally, they will use ML tools to implement strategies to evolve and scale their environments to support their business’s operations.

And as IT pro’s mature their understanding and use of machine learning-based analytics tools, they will be on the forefront of building the foundation for automation and the future of the self-driving data center.
