Cisco Application Hosting on Catalyst 9000 series of switches extends the cloud to the edge of the network enabling data processing closer to the critical source in a distributed manner. Application Hosting is used by various businesses and developers to host new breed for Security, network monitoring/troubleshooting and data analytics tools removing the need for expensive hardware or compute nodes. Catalyst 9000 series switches run on open and modular IOS-XE which is programmable. With Polaris IOS-XE 16.12.1 software release, Catalyst 9300 series switches will have native docker engine. Developers can now quickly develop docker applications and deploy them as needed, shortening the development cycle.
Code for Catalyst challenge is a platform to contribute towards developing docker based applications which are of business relevance and can run on Catalyst 9000 series switches. Current target platform would be Catalyst 9300 series switches. The timeframe for the challenge is July 16, 2019, at 12:00 a.m. Pacific Time and ends on September 13, 2019, at 11:59 p.m. Pacific Time. You can participate as an individual contributor or in group of maximum of 3. All the rules and regulations can be found here .
The intent of the challenge is to grow and nurture a strong repository of code base that can be leveraged by other users as well to drive their business intent. Writing a docker container for a Catalyst 9300 is absolutely simple and you can find the steps here . You can now validate and verify your docker applications too using Application Hosting sandbox on DevNet. Sign up now to participate in Code For Catalyst and join us on this exciting journey. There are some amazing prizes to be won too!
“We (Conscia) are excited how easy it is to quickly put Docker™instances in the network edge layer using the App Hosting on Catalyst 9000. App hosting opens up new possibilities for distributed architectures with automation and IoT with the help of local data processing in the edge" — Stefan Ehrson , Senior Network Engineer, Conscia

The network is growing and how! Data is being generated at such an exponential rate. An IDC report states that data will grow to 175 Zettabytes by 2025. With such an explosion, enterprises cannot keep sending all the incoming data directly to the cloud. There needs to be some kind of compute that happens at the edge so that only meaningful data is sent back to the cloud. In addition to this, having expensive gear to host application just increases the opex of an organization. The other important consideration is to reduce the time a developer spends on rewriting the apps. This is where Application Hosting on Catalyst 9000 switches comes into play.
Catalyst 9000 series switches were launched in 2017 and went on to become the fastest ramping product in Cisco’s history. The main driving force behind any of the innovations on Catalyst 9000 series switches has always been simplicity. Catalyst 9000 series switches run on open and modular IOS-XE which is programmable. With Polaris IOS-XE 16.12.1 software release, Catalyst 9300 series switches will have native docker engine. With native docker support, developers can quickly develop applications and deploy them where needed. We will also be introducing Application Hosting workflows within Cisco DNA Center to completely manage the lifecycle of applications to help scale the business.
Networking and compute resources are set aside for Application Hosting so that it does not affect the other processes that are running.
Front panel ports (1G)
1 core (25%)
Security is another key consideration. Cisco SSD or SATA storage is required on Catalyst 9000 switches in order to host the applications. These applications cannot be hosted directly on the flash. Cisco recommended SSD and SATA ensures security is in place. For host authentication to take place, USB password can be configured on the switch. There is also encryption via AES-256 HW encryption of the internal SATA SSD.
One of the most important considerations has been to build an ecosystem of solution partners and open source applications. With Ecosystem exchange, customers can now get an understanding of the wide array of solutions that can be leveraged to address their business needs. Solution providers can now apply to become a partner with us. In addition to this, we have now introduced learning labs and sandbox to get an understanding of the solution and try it out as well. Learning lab modules will help in overview of the solution and provide the steps to create your own docker app. Sandbox will let you host the apps of your interest and explore the possibilities.

Catalyst 9000 Series has been heralded as the torchbearer ushering an entirely new era in networking. Catalyst 9000 Series along with Cisco’s Intent Based Networking solution provides policy based segmentation, automation and assurance. Catalyst 9000 series has its footprint starting with access, all the way to the core, with Catalyst 9300 Series, Catalyst 9400 Series and Catalyst 9500 Series. With technology leadership and powerful innovations like Trustworthy Systems, Patching, Cisco UPoE, ISSU, Stackwise virtual, AVC, AVB, ETA, Stackpower and Fast software upgrade, to name a few, Catalyst 9000 series switches are the best in class. Awarded with the CRN Product of the year award for 2017, Catalyst 9000 series has already been widely deployed by 10,000+ customers. It has twice the capacity to support more users and devices, all for a lower TCO than previous generations. Continuing on this momentum, Cisco is extending its Catalyst portfolio for all campus types with the introduction of Catalyst 9200 Series Switches.
Catalyst 9200 Series switches anchor on offering right-sized switching for small-medium deployments like that of a branch . 9200 series is the only enterprise level switch that can scale to help customers with neoteric security needs. Catalyst 9200 Series, which are fixed form switches, with UADP 2.0 mini ASIC, offer security features that are highly competitive and the best in its class. It offers full SD-Access capabilities with scale that caters to the business needs of a small branch. SD-Access offers macro as well as micro-segmentation and automated quarantine-remediation. With software defined access and network assurance capabilities, managing security violations and network malfunctions becomes highly simplified.
Cisco 9200 Series switches, operating on Cisco IOS-XE software, continues to have the same software subscription licensing as that of the other Catalyst 9000 series. The platform provides advanced security features that protects the integrity of the hardware as well as the software and all data that flows through the switch.
Macsec-128 provides secure point-to-point links for integrity and confidentiality thereby mitigating man-in-the-middle attacks and denial of service. Full Flexible Netflow (FNF) with Stealthwatch can be used to gain visibility into the network and combat malware threats. Catalyst 9200 supports f irst hop security suite to harden IPv6 operations in the network. Trustworthy Systems or TWS consists of Secure Boot, Image signing, secure device on-boarding, runtime defenses, operating system validation and modern crypto. Secure Boot ensure authenticity of the software image. Image signing for counterfeit protection and to be FIPS compliant. Secure device identity prevents counterfeiting. Overall, 9200 Series places an emphasis on simplicity and robustness. In addition to the amplified security forte, all the popular security features like IEEE 802.1x that are on 2960X/XR will continue to be part of 9200 series.
The wait is over and the latest addition to Catalyst 9000 – Cisco Catalyst 9200 Series is here. Are you ready to make the switch?
