Data Center Networks FAQs

What is the Juniper Data Center Networks solution?

The Juniper Data Center Networks solution is a combination of intent-based networking automation software, best-in-class routers and switches, and a distributed security services fabric. It helps you build crash-resistant networks and boosts reliability in networks of all sizes while enabling zero-trust access control and policy enforcement across all network connections.

What components make up the Juniper Data Center Networks solution?

The solution comprises a wide range of products. Chief among them:

  • Juniper Apstrasoftware for intent-based, highly reliable network automation and lifecycle management
  • QFX, PTX, and ACX Series switching and routing platforms for best-in-class throughput and scale
  • Cloud-Native Contrail Networking, which automates the creation and management of containerized and virtualized networks
  • Juniper Connected Security distributed services fabric for creating a zero-trust data center network

What data center networking challenges does the solution address?

The Juniper solution addresses the following networking problems that plague the industry:

  • Traditional CLI and DIY automation for data center management is difficult to scale and prone to network failures. 
  • As networks scale up, they become difficult to monitor, requiring real-time data analytics to ensure continuous validation.
  • There are shortages of skilled staff, and specialists must know the tools and CLI of several vendors.
  • Dated hardware is complicated to manage and not well-suited for scaling.
  • Internal and external security incidents can cause expensive outages.

How does the Juniper Data Center Network solution address today’s data center challenges?

The solution addresses the challenges described above in the following ways:

  • Unreliable Automation – Juniper Apstra intent-based networking software automates and validates the design, deployment, and operation of data center networks, from Day 0 through Day 2+. 
  • Monitoring at scale/analytics – Using a single source of truth, powerful analytics, and root-cause identification, Apstra quickly pinpoints and resolves issues. It allows network operators to customize telemetry collection and explore and visualize the data with an easy-to-use, no-code Graph Explorer.
  • Skillset shortages – Juniper Apstra is the only multivendor data center automation software of its kind. It does away with a CLI and hence the need for vendor-specific skills, so you can hire flexibly without vendor certification limitations. 
  • Hardware management and scalability – QFX Series Switches deliver industry-leading throughput and scalability, the open programmability of the Junos OS, and a broad set of EVPN-VXLAN and IP fabric capabilities. Combined with the management prowess of Apstra, they’re an optimal choice in enterprise, service provider, and cloud provider environments.
  • Security threats – The data center solution works with the Juniper Connected Security distributed services fabric of physical, virtual, and containerized SRX Series Firewalls to deliver a zero-trust experience. Protection extends across users, applications, and data wherever they are, in the data center, network edge, or the cloud.
