3 Signs Your Relational Database Must Go

Application and operations teams sometimes reach a point where they must upgrade the database. Whether it’s due to data growth, lack of throughput, too much downtime, the need to share data globally, adding ETLs, or otherwise, it’s never a small project. Since these projects are expensive, any recommendation requires a solid justification.  This article a) characterizes 3 signs where traditional databases hit a wall, b) explains how vFabric SQLFire provides an advantage over traditional databases in each case, and c) should help you make a case for moving towards an in-memory, distributed data grid based on SQL.

For those of us tasked with upgrading (or architecting) the data layer, we all go through similar steps. We build a project plan, make projections and sizing estimates, perform architecture and code reviews, create configuration checklists, provide hardware budgets and plans, talk to vendors about options, and more.  Then, we work to plan the deployment with the least downtime, procure hardware and software, test different data load times, evaluate project risks, develop back-up plans, prepare communications to users about downtime, etc. You know the drill. These projects can take months and consume a fair amount of internal resources or consulting dollars. If you are starting or working on one of these types of projects with a traditional database architecture in mind, are you considering these 3 signs as you consider your options? Continue reading

Sizing vFabric GemFire – VMware’s Java-based, Spring-Enabled, In-Memory Data Platform

Capacity planning in the enterprise is no easy task. In this post, we provide an overview for sizing VMware’s elastic, in-memory data management product, vFabric GemFire and a link to an in-depth, technical article.

Setting the Stage for Memory Sizing

Enterprise applications today are distributed systems that have to satisfy increasingly more complex business requirements. When the ever growing demand for managing more data is added, the task keeps getting harder.

One of the key factors in capacity planning for memory intensive systems, such as in- memory data stores, is memory capacity. Even though the price of memory keeps going down, data capacity requirements keep going up, and this makes memory as precious a resource as ever. As large systems become even larger, it becomes more important to manage this resource efficiently. In addition to obvious reasons, such as Total Cost of Ownership (TCO), there are technical challenges that come with large memory pools. For one, garbage collection (GC) takes more time, which can affect both latency and throughput. Determining memory requirements correctly is both crucial and difficult.

That is why this post and the related technical article focus on memory sizing and provide concrete guidelines for determining required memory for optimal performance, especially in large scale vFabric GemFire deployments. GemFire has facilities that can be very useful for memory sizing. The article not only explains the facilities, but also describes a method and guidelines to take the guesswork out of memory sizing process. Continue reading

Using Visual Statistics Display to Analyze GemFire Runtime Configuration, Resources, and Performance

vFabric GemFire is a sophisticated product in a complex problem space: data management in distributed systems. In order to help our users get the most out of GemFire, we are starting a “cookbook” series, which will provide tried and tested recipes that we hope every GemFire user will find useful.

Our first topic is the Visual Statistics Display (VSD). VSD is a visual tool for analyzing GemFire statistics. It reads GemFire statistics from special statistics archive files created by GemFire, and renders their graphs for analysis. It is not a real-time online monitoring tool, such as vFabric Hyperic, so it does not have the real-time monitoring and alerting capabilities that they have. On the other hand, it is the most powerful tool for examining the state of a vFabric GemFire system, as it provides access to all the statistics collected by GemFire. No real-time monitoring tool can do that, as the amount of statistics that GemFire collects is prohibitive for real-time collection in a distributed system.

Field Report VMworld Europe Day 3

Over 37,000 VMs have been started in Hands on Labs. Hands on Labs run in Hall 6 through Thursday. vFabric labs include Application Director, Data Director, CloudFoundry, SQLFire and scaling with vFabric.

As noted in the Field Report from Day 2, we greatly appreciate the opportunity to listen and learn from our VMworld Europe customers, prospects, and partners! VMworld this year has not dissapointed. We’ve met with hundreds of partners, thousands of customers and spun up tens of thousands of virtual machines in our hands on labs. Over 37,000 in fact at the start of Wednesday, with two more full days to go! An impressive event all around.

Not surprisingly after the keynote yesterday, customer discussions have continued on Application Director, with many stating explicitly that they are going to use this as the cornerstone opportunity to build out a self-service infrastructure, just like VMware’s own IT did.

Beyond that, a few other key themes have emerged:

Significant vFabric Interest from VMware Partners
Monday was a partner day, and there is a lot of interest in vFabric from partners.  They are looking to VMware to learn and improve how they are building apps for their customers in cloud environments. For one of our presentations on Monday, we had a packed house with over 100 people in the audience.
