Cisco targets hyperscalers with silicon, high-end routers

    Cisco says it wants to change the future of the Internet and has rolled out the new silicon, hardware and software it says will move toward that goal.

    The centerpiece of Cisco’s strategy revolves around its custom Silicon One chip technology and new Cisco 8000 Series carrier-class routers built on that silicon, which the company says has been in development for more than five years, at a cost of over $1 billion. The 8000s feature a new operating system – IOS XR7 that runs the boxes and handles security.

    The Cisco Silicon One Q100 optical-routing silicon brings up to 10Tbps of network bandwidth in its first iteration – with a future goal of 25Tbps – and support for large non-blocking distributed routers, deep buffering with rich QoS and programmable forwarding.

    Cisco goes deep into AWS hybrid cloud with SD-WAN, security, Outposts data center support

      Cisco is taking its integration with Amazon Web Services to a new level, announcing plans to integrate its SD-WAN, network services and security wares with the cloud giant’s hybrid-cloud environment, including its new Outposts devices.

      Outposts offers AWS-designed hardware that lets customers run compute and storage on premises, while connecting to AWS’s cloud services. Each Outpost has a pair of networking devices, each with 400 Gbps of connectivity and support for 1 GigE, 10 GigE, 40 GigE, and 100 Gigabit fiber connections. AWS announced the general availability of Outposts at its annual AWS re:Invent symposium, held this week in Las Vegas.

      How Arista’s New Cloud Networking Features Fit NetDevOps

        A few days ago, Arista Networks announced a couple of new cloud networking features that enable companies to move to a NetDevOps management model. For those not familiar with the term “NetDevOps,” here’s an explanation: As the name implies, it brings DevOps principals to network operations with the ultimate goal of running a network as agile as running cloud infrastructure.

        The challenge is that network infrastructure was never designed with agility in mind. In fact, one could argue the traditional vendors purposely kept the complexity high to drive up the amount of service and support that networks required

        Arista announced cloud networking capabilities that enable streamlined operations for running virtualization and containers in hybrid, multi-cloud environments. Its new CloudEOS operating system has an integrated VM that makes it easier to spin up network resources to create dynamic connections between on-premises and public clouds and between public cloud providers. This allows network traffic to be continually directed to the best path as determined by a number of network attributes, including analysis of the telemetry information available in EOS.

        Object storage in the cloud: Is backup needed?

          The failure to back up data that is stored in a cloud block-storage service can be lost forever if not properly backed up. This article explains how object storage works very differently from block storage and how it offers better built-in protections.

          What is Object Storage?

          Each cloud vendor offers an object storage service, and they include Amazon’s Simple Storage Service (S3), Azure’s Blob Store, and Google’s Cloud Storage.

          Think of object storage systems like a file system with no hierarchical structure of directories and subdirectories. Where a file system uses a combination of a directory structure and file name to identify and locate a file, every object stored in an object storage system gets a unique identifier (UID) based on its content.
