Managers struggle with priorities and must juggle user requirements and deadlines against staff availability and expertise. Here is one way to manage DBA tasks based on the makeup of the team.

A Decade of Dynamo: Powering the next wave of high-performance, internet-scale applications

All Things Distributed

Today marks the 10 year anniversary of Amazon's Dynamo whitepaper , a milestone that made me reflect on how much innovation has occurred in the area of databases over the last decade and a good reminder on why taking a customer obsessed approach to solving hard problems can have lasting impact beyond your original expectations. We had an advanced team of database administrators and access to top experts within Oracle. This was the genesis of the Amazon Dynamo database.

Amazon Web Services AWS – Accelerate Your Cloud Success

Galido

Web administrations are here and there called cloud administrations or remote figuring administrations. The primary AWS offerings were propelled in 2006 to give online administrations to sites and customer side applications. Distributed computing is the on-request conveyance of process power, database stockpiling, applications, and other IT assets through a cloud administrations stage by means of the web with pay-as-you-go evaluating.

Are You Agile Enough for Polyglot Programming?

I am also fluent in ten markup languages, 8 frameworks, and seven database languages on six different platforms. Aren’t most applications are written just in just language? However, today we write composite applications, with multiple components running on different systems and different platforms. The old model view controller paradigm is split up across Web servers application servers and database servers all tied together by some sort of message bus and a network.

Oracle and EMC Help Protect Against Silent Data Corruption.

Chuck's Blog - EMC

  An application sends a perfectly formed write to the storage array, but the bits get scrambled along the way.    Reads and writes flow from database to storage through a SAN.  The likelihood of a problem occurring is somewhat proportional to the number of writes being done; a heavy write-intensive transactional database such as Oracle is more exposed than, say, a user file system.  Chucks Blog.

When Generic IT Infrastructure Doesn't Cut It

Chuck's Blog - EMC

I'm guessing it's databases, and the applications that use them. If your business is heavily invested in databases, maybe mainstream generic infrastructure thinking isn't doing you any favors. If you're like most enterprises, databases are at the very heart of your business. Statistically speaking, more often than not these are Oracle databases. Now think about all the applications that interact specifically with the database.

Building A SDS Conceptual Model — Part 1

Application Centricity — And Policy. It’s not just a buzzword, it’s largely why IT exists in the first place: to deliver the applications that people want to use.   In any SDDC (or SDS) discussion, we start with the needs of applications (or logically related groups of applications, if you prefer), and work downwards.      At a high level, I think of an application as comprised of logic, data, resources required — and policy.
