Monitoring and Visibility for the Hybrid Cloud

Today’s hybrid architectures require a combination of monitoring techniques to create a modern, full-stack, hybrid cloud monitoring capability.

3 Ways Docker Customers Future-Proof Legacy Windows Server Applications

In 2018, why are we still talking about legacy Windows applications? Why are we holding onto Windows Servers that are a decade old? The simple answer — the applications on those servers still work, and they still serve a business purpose. But they can become a significant liability.

Many of our customers are containerizing legacy Windows 2003 and 2008 applications today with Docker Enterprise, making them portable to new Windows Server platforms and the cloud with no code changes. These three examples — Jabil Circuit, a bank, and GE Digital, showcase the depth of what you can do with Docker Enterprise to modernize legacy Windows applications.

Jabil Modernizes Legacy Windows Apps for Cloud Migration

Jabil, one of world’s most technologically advanced manufacturing solution providers with over 100 sites in 29 countries, has embarked on a digital journey to modernize their technology infrastructure. They have a “cloud-first” strategy that requires modernizing over 100 legacy .NET and Java applications, many of which are running on Windows 2008 and 2012.

They’ve deployed Docker Enterprise and windows containers to successfully migrate the applications from legacy Windows servers to Windows Server 2016 on Microsoft Azure cloud. Now that the first phase is complete, Jabil has Continue reading

Upcoming Webinars and Events: October 2018

The fast pace of webinars continues in October 2018:

Rachel Traylor will talk about graph theory and its relevance to reliable network design on October 8^th;
The Amazon Web Services Networking webinar will start on October 11^th. The second session is planned for October 25^th;
On October 16^th we’ll have the third session of VMware NSX technical deep dive (unless I manage to finish on time later today… not likely).

There are no on-site events planned until early December:

We’ll run another on-site workshop in Zurich on December 5^th . This time we’ll focus on using VXLAN and EVPN to build multi-site fabrics;
I’ll talk about making SDN better with IPv6 on December 6^th.

You can attend all upcoming webinars with an ipSpace.net webinar subscription. Online courses and on-site events require separate registration.

AWS ABCs — EC2 Internet Connectivity

So, you've created a compute instance (ie, a virtual machine) on Amazon EC2. Next question: does the instance require access to and/or from the Internet?

Protip: just because you created the instance in the public cloud, i.e. the cloud that you get to over the Internet, it doesn't mean that your instances all need to sit on the Internet. They can have direct inbound and outbound Internet access, no Internet access, or something in between (which I'll explain).

The basic building block for networking on AWS is the VPC (Virtual Private Cloud). Within a VPC, you define your IP space, gateways, ACLs, DHCP options, and more. Gateways will be the focus of this article.

Reference Guide Update: Deploying NSX Data Center on an ACI Underlay

NSX Data Center is now the de facto SDN standard for the Private Cloud. Reference guides for NSX Data Center are proven to reduce complexity in managing the physical switch infrastructure. This increases the infrastructures stability and requires a minimal set of system and service configuration to bring up the fabric. Organizations utilize NSX Data Center for a diverse set of use cases including security, a diverse application framework deployment platform, and application continuity across private and hybrid clouds. With reference designs for any underlay, NSX Data Center is fulfilling its promise to be a platform over any infrastructure. NSX Data Center provides the cornerstone for the Virtual Cloud Network.

Overview of NSX Data Center with ACI Underlay

Ever since publishing our original design guide Deploying NSX with Cisco ACI as an Underlay, there has been an avalanche of interest in building out a more simplified Cisco infrastructure with ACI as the underlay. Most of the requests are for more detail when constructing the ACI underlay. The high-level design guidance in the original NSX reference design for ACI discussed the minimum ACI constructs necessary for an NSX Data Center deployment. These ideals have not changed. The original paper called Continue reading

Will Operators Use Alternative Backhaul Technologies to Deliver on 5G?

WiFi, fixed access, and satellites are promising technologies that operators should consider as viable alternatives to fiber or microwave for 5G backhaul.

Intel makes a play for high-speed fiber networking for data centers

Intel is revamping its strategy around the data center by going beyond the Xeon chip and into silicon photonics transceivers. The company announced Monday at the European Conference on Optical Communications (ECOC) that samples of its silicon photonics transceivers targeting 5G wireless infrastructure and data centers are available now, with production set to start in the first quarter of 2019.The company notes that global data center IP traffic is increasing significantly. In 2016, global data center IP traffic was 6.8 zettabytes, and that will triple by 2021 because of all this data generated by humans and the Internet of Things (IoT).The choke point becomes copper wire, the standard for Ethernet connectivity. Copper wire can only effectively transmit about eight to 10 meters, said Eoin McConnell, director of marketing for the connectivity group in Intel’s data center group. Fiber optics can go as far as 10 kilometers.To read this article in full, please click here
