openstack foundations

    OpenStack Foundations The key to cloud computing is decoupling virtual resources from physical ones. The ability to abstract processors, memory, etc., from the underlying hardware, enables on-demand/elastic provisioning and increased efficiency. This abstraction process has driven the cloud and led to various popular cloud flavors such as IaaS …

    VIPTELA SD-WAN Problem Statement WAN edge networks sit too far from business logic and are built, and designed with limited application and business flexibility. On the other hand, applications sit closer to business logic. It’s time for networking to bridge this gap using policies and business logic-aware principles. …

    Network Configuration Automation Automate Network Configuration How applications are deployed today is so different from the way applications were deployed 10-15 years ago. So much has changed with the app. The problem we are seeing today is that the network is not tightly coupled with these other developments. …

Nested Hypervisors

    Nested Hypervisors When considering nested hypervisors, from the perspective of cloud migration, two main types of cloud applications exist; Cloud-Centric & Cloud-Ready. Cloud-centric applications are “born for the cloud,” built as greenfield cloud application stacks, meeting all cloud requirements. On the other hand, cloud-ready applications must be redesigned or changed in …

On 27th of July, Gartner published its annual Hype Cycle for Networking and Communications. It assesses network technologies that are most relevant and scores them on benefits rating and maturity levels. Key areas that are at “Peak” levels are SD-WAN, WAN Optimizations, SDN Applications, Cloud Managed Networks and White-Box switching. Markets …

IDS IPS Azure

    IDS IPS Azure Microsoft Azure Cloud consists of functional design modules and services such as Azure Internet Edge, Virtual Networks (VNETs), ExpressRoute, Network Security Groups (NSGs) & User Defined Routing (UDR). Some of these resources are controlled solely by Azure; others are within the customer’s remit. The following …

SDN applications

HP SDN Controller

    HP SDN Controller It takes too long to provision network services for an application. As a result, the network lacks agility, and making changes is still a manual process. Usually, when an application is rolled out, you must reconfigure every device with a command CLI interface. This type …

Azure ExpressRoute

    Azure ExpressRoute There is increasing talk about the cloud, what it can do for business and how you connect to it. Any cloud can be connected via untrusted Internet or a private direct connection. For direct connectivity, AWS has a product known as AWS Direct Connect, and Microsoft …

Segment Routing

    Segment Routing So, what is segment routing? Firstly, before we start discussing a segment routing solution and the details of segment routing vs MPLS. Let us recap how MPLS works and the protocols used. MPLS environments have both control and data plane elements. A BGP-free core operates at …

WAN Virtualization

WAN Virtualization

    WAN Virtualization Deploying and managing the Wide Area Network (WAN) has become more challenging. Engineers face several design challenges, such as traffic flow decentralizing, inefficient WAN link utilization, routing protocol convergence, and application performance issues with active-active WAN edge designs. Active-active WAN designs that spray and pray over …

Application Delivery Controllers

    Application Delivery Network Compared to 15 years ago, applications exploded when load balancers first came on the scene. Various content such as blogs, content sharing, wiki, shared calendars,s, and social media exist that load balancers ( ADC ) must now serve. A plethora of “chattier” protocols exist with …

data center topology

    Some data center vendors offer a “Debian” based operating system for network equipment. Their philosophy is that engineers should manage switches just like they manage servers with the ability to use existing server administration tools. They want networking to work as a server application. For example, Cumulus has created the …
