How-To: Build a Geographic Database with PostGIS and vPostgres

Mobile Location Based Services are on the rise. After several false starts back in the mid 2000s, every mobile user now depends on their phones to tell them where they are, where their friends are, and to engage with social media like Facebook and Foursquare.  A report by Juniper Research suggests this market is expected to breach over $12 billion next year, where it hardly existed a few years ago at all.

This is in part because mobile apps have become ubiquitous now. In order to remain relevant, businesses need to interact socially and have a web store to remain accessible to their wandering customers.

Building a geographically aware application from scratch sounds daunting and like a lot of initial data setup. It doesn’t have to be. Products like vFabric Postgres (vPostgres) can be used along with the PostGIS extensions to perform geographic-style queries. Then,  public data and an open source visualizer can be used to transform the query into a meaningful result for your application or end user.

Disaster Recovery Jackpot: Active/Active WAN-based Replication in GemFire vs Oracle and MySQL

Ensuring your systems run smooth even when your data center has a hiccup, or a real disaster strikes is critical for many companies to survive when hardships befall them.  As we enter the age of the zettabyte, seamless disaster recovery has become even more critical and difficult. There is more data than we have ever handled before, and most of it is very, very big.

Most disaster recovery (DR) sites are in standby mode—assets sitting idle, waiting for their turn. The sites are either holding data copied through a storage area network (SAN) or using other data replication mechanisms to propagate information from a live site to a standby site.  When disaster strikes, clients are redirected to the standby site where they’re greeted with a polite “please wait” while the site spins up.

At best, the DR site is a hot standby that is ready to go on short notice.  DNS redirects clients to the DR site and they’re good to go.

What about all the machines at the DR site?  With active/passive replication you can probably do queries on the slave site, but what if you want to make full use of all of that expensive gear and go active/active?  The challenge is in the data replication technology. Most current data replication architectures are one-way. If it’s not one-way, it can come with restrictions—for example, you need to avoid opening files with exclusive access.

PostgreSQL Security Release Now Available

IMPORTANT SECURITY UPDATE NOW AVAILABLE

Download VMware vFabric Postgres Security Update
Download immediately

The PostgreSQL Project has released an important security update for all supported versions including v9.2.4, v9.1.9, v9.0.13, and v8.4.17. Likewise, VMware has also released updated versions of the vFabric Postgres distribution.

This release includes a fix for a high-exposure security vulnerability (CVE-2013-1899) that is considered so important, the PostgreSQL project pre-announced this release last week and closed development to protect the vulnerability from being exploited before the threat had an update readily available to protect users against it.

All users are strongly urged to apply the update as soon as it is available. Continue reading

How to Perform Security Updates on vFabric Postgres

The PostgreSQL community announced last week that an important security update will be released on April 4, 2013. This release will include a fix for a high-exposure security vulnerability and all users are strongly urged to apply the update as soon as it is available. Knowing how disruptive urgent security updates can be to IT and developers, the PostgreSQL community issued advanced warning in the hopes that it would ease the impact to day-to-day operations while helping as many companies as possible to adopt the update quickly.

As such, we would like to take the time to remind us all how important these security updates are to your business, and how to apply them most efficiently for vFabric Postgres.

The Cost of Missing Security Updates

Maintenance and security software updates are essential in extending application longevity as well as in keeping the confidence of customers who use services based on the application.

When big data disasters hit, the impacts quickly move beyond financial and affect reputation and trust. Databases are a particular area of concern. A recent article titled, “Making Database Security Your No. 1 2013 Resolution,” cited a Verizon study that showed only 10 percent of total security spend goes into database protection, while 92 percent of stolen data comes out of databases.

According to the seventh annual U.S. Cost of a Data Breach report from Ponemon Institute, the cost of an average data breach was $5.5M in 2011 or $194 per record. While $5.5M may not sound like a lot to some companies, losing one million records at a cost of $194 per record adds up. Continue reading

New Serengeti Release Extends Cloud Computing Support for Hadoop Community

Today VMware is releasing a significant new release of their big data virtualization open source project Serengeti called M4 or version 0.8.0. Designed to help make it easier for Hadoop users to deploy, run and manage mixed workload clusters on a virtualized platform, this release broadens support across the various distributions of the Hadoop community, including new support for Cloudera CDH4, MapR, and HBase. Additionally as part of this release, Serengeti M4, includes updated performance configuration improvements and a hardware reference architecture guide.

This release comes at a perfect time for an exploding data market. This year, worldwide we will create 4 zettabytes of new data, and more than 80% of that will be unstructured data that does not work in a traditional database management system. At the same time, businesses are learning to harness that data and use it to better their business.

A popular strategy to succeed in the data market is Hadoop, an open source data framework that that allows for the massive distributed processing of large data sets across clusters of nodes using simple programming models.  Additionally, Hadoop offers a scalable file system (HDFS) that allows users to store huge amounts of data leveraging inexpensive disks on commodity servers.  The powerful framework has spawned many new startups in Silicon Valley and has Enterprise IT departments clamoring to harness the power of this technology. Huge web applications like Facebook, LinkedIn, Yahoo! and eBay all rely on Hadoop to process and store data for hundreds of millions of users. Continue reading

1. Modernizing Legacy Apps to Cloud and SaaS with vFabric

“In vFabric we see a very attractive modern cloud application platform.  So while spring and vFabric represent very attractive alternatives for new application development, what we see with our clients are is the desire to modernize and transform existing applications to take advantage of those same benefits of vFabric.  The run time benefits, the design time benefits.”—Chase Crawson, Director of Application Services, CSC Continue reading
