Epsilon, ESPs, the Cloud and You

While the IT industry is in many ways moving toward an outsourced model, with the widespread adoption of the cloud and XaaS, marketing has been moving in a similar direction as well. And while PR agencies have been around for quite some time and it has been normal to look to outside agencies for help with creatives, over the past several years a new kind of service provider, the Email Service Provider, or ESP, has emerged from the shadows. Not to be mistaken for cloud-based email security services, ESPs are in the business of sending mass email (typically opt-in), not blocking it. Unfortunately, for many, their first exposure to these companies (outside of an inbox full of enticing offers) has been via news around data breaches, first, in 2010 with Silverpop and now Epsilon.

DCI Use Case: Capacity Expansion

Hi,

Today I want to bring up DCI use case that I’ve been thinking about: capacity expansion.  As you know, the purpose of DCI is to connect two or more Data Centers together so that they share resources and deliver services.  The capacity expansion use case is when you have temporary traffic bursts, cloud bursts, either planned or unplanned, maintenance windows, migrations or really any temporary service event that requires additional service capacity.

To start addressing the challenge of meeting these planned and unplanned cloud burst and capacity expansion requirements, check out the new ACE + OTV feature called Dynamic Workload Scaling announced recently.

What Cisco’s New Data Center Switching Announcements Mean for Service Providers

Cisco’s foundation for delivering the service provider Cloud is our Unified Service Delivery (USD) solution, featuring tightly integrated, data center and IP NGN technologies to deliver a virtualized end-to-end infrastructure for cloud services. We thought it would be useful to share some new capabilities that Cisco has added recently to the solution:

MPLS in the Data Center: To streamline the end to end operation across the data center and IP NGN,  Cisco announced, last week, that Nexus 7000 supports Multi Protocol Label Switching (MPLS) for Layer 3 virtual private networks (VPNs). This allows MPLS to be deployed  at the data center core/aggregation layer  rather than terminating at the data center edge. This capability enables Service Providers to greatly simplify L3 segmentation, especially for multi-tenant cloud offerings, depending on their scale and service needs.

Another key to the delivery of a data center built for Cloud requirements of scale, virtualization and multi-tenancy has been the use of a Unified Fabric. Unified Fabric provides the flexibility of high performance, highly available networks to support the needs of both LAN and SAN on a consolidated fabric. Cisco’s Unified Fabric announcements last week bring new capabilities which extend our already robust offerings to further build out a Service Provider Cloud foundation.

Cisco Partner Update: Spring Break Survival Guide

April 1, 2011 at 10:19 am PST

Andrew and I missed our college days so much that we decided to join the spring break revelers and film Partner Update from sunny Coronado Beach in San Diego, California. In this episode, we’ll be delving into such important spring break topics as:

  • SPF 15 vs. SPF 20? Choose the right SPF for you!
  • Survival Guide: What to do if your friends bury you under sand while you’re napping.
  • Salt water – more nutritious than you realize.

Watch our special “Spring Break Survival Guide” edition of Partner Update.

Does the Data Center Provide an Advantage for Government?

Today, as I watched the Cisco Data Center webcast “Evolutionary Fabric, Revolutionary Scale: A Nondisruptive Way to Handle Dynamic Data Center and Cloud Environments” I thought about how data centers can provide an advantage for government agencies seeking ways to increase operational efficiency and reduce costs.

In many ways, data centers today have similar characteristics when compared to government organizations with:

  • isolated silos of information
  • labor-intensive manual processes
  • rising costs of service
  • limited flexibility
  • mandates to provide open access to information
  • changing workplace with mobile applications, video, …
  • requirements to ensure security

In the data center, silos include servers, storage, applications, and network devices.  In many government organizations, different agencies often operate independently in separate silos.

The strategic advantage for both government IT organizations and government agencies is to develop holistic strategies that unify the separate parts into a system to deliver better efficiency with higher resource utilization that is easier to manage and costs less.
