A Look Back at 2014 and Innovation at Juniper Networks

by Juniper Employee ‎12-17-2014 03:33 PM - edited ‎12-18-2014 04:13 PM

pathcloud - small.jpgAs the year comes to an end it’s always interesting to look back at the changes in the industry and the progress that we made as a company in the last year. There were many trends that emerged or took further hold of the industry in 2014. Let’s take a look at them and see how Juniper delivered innovation in these areas. Cloud computing and the need for on-demand resources was a big one. The open source movement is continuing to grow in the cloud space and OpenStack and CloudStack are gaining momentum. The Dev/Ops movement and the need for automation of IT resources was another big trend in the news. We saw Dev/Ops extend to networking equipment like the top of rack switch, when it had previously been mainly for server configuration. Overlay networks took hold in 2014 with the likes of Juniper’s Contrail and VMware’s NSX gaining momentum. New network fabric architectures were introduced like IPClos that is popular with the MSDC’s or Massively Scalable Data Center Operators and Spine and Leaf architectures that offer simplified deployment and management. The rise of the Open Compute Project and its move to include networking was a bit of a surprise for me. There is certainly something going on there.

Enterprise IT is moving away from acting as siloed service organizations to aligning with the business’ goals to help their organizations enhance their business agility, value and customer experience. Many of these organizations are moving to a cloud computing model to achieve these goals, but they haven’t determined the best strategy for making this transition.
Transitioning to the cloud will help these organizations accelerate innovation and business agility by emphasizing a number of important factors.  Adaptability is one.  Seamless scale, both upward and downward, is another. Network intelligence that will provide proactive resource optimization is a third.

Lock in or Look Forward – It’s Your Choice

by Juniper Employee ‎09-09-2014 05:00 AM - edited ‎09-11-2014 10:48 AM

Infographicsmall.jpgAt Juniper, we believe that networks should be open.  Vendors shouldn’t lock their customers into propriety architectures.

The way we see it, evolution shouldn't have to hurt.  You should have the freedom to start with one architecture and then migrate to another over time as your needs change. This should be an easy process, with no hidden costs or restrictions.

A Network Fabric for New Applications in the Data Center

by Juniper Employee ‎04-24-2014 05:13 PM - edited ‎04-25-2014 09:05 AM

vcfpic-2.pngThanks to virtualization organizations can bring up new applications and services quickly. Unfortunately, many data center networks don’t let you fully capitalize on the business agility that virtualization and modern application architectures provide. Traditional network architectures are too slow and too cumbersome to configure. For true agility, enterprises need a high-performance, low-latency fabric network that can be managed like a single, logical switch.

Organizations are going through a transition in how they build network infrastructure. This is because the number and type of applications in use is growing rapidly. The way that applications are accessed is changing and so is the way that they are designed.

 

Organizations are hosting applications in their own data centers. They are extending their applications across data centers. They are accessing applications from cloud hosting providers. Service providers are hosting applications on behalf of the enterprise and providing application management services.

 

These new applications are complex and they are virtualized and many of newer ones are SDN enabled. Many applications are used in multiple geographies and workloads follow the sun. All of this is changing how applications need to be delivered and how the network needs to be build to serve them.

The Critical Role of the Business Edge Network

by Juniper Employee ‎03-02-2014 06:15 PM - edited ‎03-02-2014 07:04 PM

Businesses are increasingly using service providers to host critical applications and data in order to better control the security and availability of the data and to mitigate the expenses associated with hosting and serving data locally to the entire business user base. They access these applications and data over the service provider’s business edge network. This creates a challenge for the service provider, because their customers measure the success of the network by its ability to handle critical data and provide a superior user experience. With more and more applications and data centralized, the importance of the network, and its role in the success of the business, becomes ever more critical.

Does E-VPN Spell the End for OTV?

by Juniper Employee ‎02-28-2014 12:05 PM - edited ‎02-28-2014 01:24 PM

corevsedge2-1.pngIf you are considering how best to do Layer 2 stretch for virtual machine mobility, then you might be considering Overlay Transport Virtualization (OTV). OTV designed by Cisco to offer L2 stretch with what they said was an easy to deploy protocol. It was only available on the Nexus switching product line, which didn’t support VPLS/MPLS. Until recently MPLS/VPLS was Juniper’s recommended technology for network segmentation and Layer 2 stretch, which Cisco also offers on the ASR routers.  We’ve recently announced E-VPN, which is MPLS/VPLS based and brings all of the benefits of VPLS and then some. Cisco has announced E-VPN on the ASR router as well. Now that E-VPN is available, maybe it’s time to consider your best option. Let’s take a look at why OTV isn’t the best choice for VM mobility and why E-VPN is.

Enhancing VM Mobility with VxLAN, OVSDB and EVPN

by Juniper Employee ‎12-13-2013 06:51 PM - edited ‎02-18-2014 05:28 PM

epvnvxlan-2.pngOrganizations are increasingly using virtual machine mobility to optimize server resources, ensure application performance and to aid in disaster avoidance. Typically VM live migration has relied on increasing the scale of the L2 broadcast domain to ensure that the VMs can be reached after migrations using their current addressing. This has resulted in the increasing use of VLANs and the need for L2 extension over the WAN.  As a result organizations are looking for ways overcome the limitations with VLAN scale and for methods to extend the L2 domain over the WAN that ensure the best performance. VxLAN has emerged as an alternative technology to VLANs, and EVPN has emerged at a better way to transport VMs over the WAN. Together these technologies can enable VM live migration over the WAN, or long distance Motion in VMware parlance, but they need to all work together effectively and this is where OVSDB, VxLAN routing and a new technology from Juniper called ORE come in to play.

Optimizing EVPN for Virtual Machine Mobility over the WAN

by Juniper Employee ‎12-06-2013 05:49 PM - edited ‎12-07-2013 06:20 PM

vmto-2.pngOrganizations need to insure that their applications are available and performing. Server virtualization helps by enabling virtual machine mobility.  If a server is overworked or will be unavailable vMotion can be used to migrate live workloads to another server in the current data center or in another data center. This requires that the addressing including the MAC, IP address and VLAN ID remain the same so that sessions are not dropped when the VM move happens. This is done by extending the L2 domain to the new location, know as Layer 2 stretch. Within a subnet this is easy to do. Across subnets in the data center it becomes more difficult. Doing live migration over the WAN introduces considerable challenges. Juniper has introduced a number of technologies to make virtual machine live migration possible.

What it means to simplify data center operations with MetaFabric

by Juniper Employee ‎12-01-2013 11:46 PM - edited ‎12-02-2013 07:19 AM

In conversations with customers across the Asia Pacific, one recurrent topic has been the constant uphill battle they face in managing the complexity of their IT environment with limited IT resources. As their organisations grow, the traditional approach to connecting more users and servers and rolling out more applications, has been to deploy more ports and switches. This has inevitably led to a proliferation of interconnected devices resulting in more devices to manage and troubleshoot.

Sorting Out the News and Making the Right Choices

by Juniper Employee ‎11-13-2013 02:40 PM - edited ‎12-16-2013 02:45 PM

meta1-small.pngAs we look back on the last couple of weeks there was a lot of news about networking that we are still taking in. The networking industry is evolving and there are important considerations to make as you build out your networks. We are seeing an ever increasing need for bandwidth, a need for greater application awareness and the need to quickly provision, trouble shoot and adapt the network to ensure application performance and availability. As a result we are seeing a transition to software defined networks. If you are building networks to serve your business then you are probably considering how your choices today will affect your ability to respond to the changes that come in the future. How do you get to where you need to be? What is best for your organization?

Connecting Islands of Resources in an SDN Data Center

by Juniper Employee ‎10-28-2013 08:51 PM - edited ‎08-26-2014 07:43 AM

sdn-gw - small.pngOrganizations are rolling out new applications that they use to drive the business. These applications are virtualized. They are increasingly distributed, dynamic and they can span locations. They connect employees, customers and the supply chain. They make employees more productive, help customers to engage with the business and facilitate better inventory management. They also provide timely business intelligence. This means revenue to the organization. Time to deploy is critical. Organizations need to be agile when it comes to deploying new applications.

If your organization is going through a data center transformation project you are probably looking at your options for switching infrastructure. As you design your network to support the move to virtualized compute infrastructure and the roll out of new application deployments the choice of switching infrastructure becomes a critical decision. One of the most versatile switching platforms on the market is Juniper’s QFX Series 10GbE/40GbE devices.  I’ve had the opportunity to talk with many of our customers about the projects that they are using the QFX switches for and why they chose it over the other options in the market. I’d like to share these examples with you.
