Data center migrations are inevitable as organizations experience data center growth through new IT applications, evolving performance and reliability requirements. Conversely, the number of data centers may shrink as the business divests certain IT requirements or applications. Juniper® Apstra enables network architects to easily preview and validate network designs without any physical or virtual infrastructure resources.
Juniper Networks® Apstra Automated Data Center Migration Service is designed to apply this simple and reliable approach to perform migrations from production data centers to next-generation data centers with significantly reduced time, cost, and risk of migration.
Data center migrations require relocating critical applications and data quickly, reliably, and with minimal or no disruption. It’s a daunting task for network architects to add migration and/or conversion strategies onto their everyday responsibilities of designing, deploying, and operating new data center infrastructure. Juniper Apstra uses software-only, multi-vendor, intent-based networking solution to ease the pain of data center migrations for both business leaders and network architects by reducing the time, risk, and cost associated with such actions.
Juniper Networks® Apstra Automated Data Center Migration Service is designed to support enterprises, cloud providers, and service providers that are migrating from existing production data centers to next-generation data center networks of all designs. Service offers easy-to-use migration packages using highly validated data center reference designs for network architectures such as 3-stage Clos or collapsed fabric. The service also offers fully customizable migrations for more advanced scenarios of data center reference designs such as 5-stage Clos. Additionally, the service allows fully customizable migrations for specific, or out-of-the-box topologies not covered by the data center reference designs, by using highly flexible Freeform reference designs to leverage any feature, protocol, or architecture.
There are two easy-to-use migration packages supported by the service, Side-by-side migration, and In-place migration. They provide complete small-scale migrations and enable customers to continue larger scale migrations, if necessary, and assume day-2 operations in the production environment. Side-by-side migration and In-place migration packages are fixed price and fixed scope-of-work which uses a highly validated data center reference design. Packages are designed for the migration of single data center (1 DC) with up to 2x10 spine-and-leaf redundant configuration for 3-stage Clos Ethernet VPN (EVPN) / IP Fabric with Edge-routed bridging (ERB) network virtualization overlay or collapsed spine network architecture. Packages support fixed number of virtual elements such as virtual networks, Data Center Interconnect (DCI) or EVPN/VXLAN gateway for layer 2 and layer 3 connectivity and fixed number of maintenance windows. Migration packages allow scalability with multiple add-on options. Customized migration option of the service offers an easy progression toward more complex migration scenarios.
This service gives your organization access to data center deployment experts with extensive knowledge of Juniper products and technologies. The service employs proven best-practice migration methodology and tools that provide a high degree of assurance, faster completion speed, and reduced migration risks. It enables you to leverage the Apstra benefits of life-cycle management features from device operating system upgrades, simple device deployments, pre-deployment data center modeling, device telemetry, analytics dashboards, to powerful Intent-Based Analytics and Time Voyager.
|Functionality||Side-by-Side Migration||In-Place Migration|
|Migration Method||Brownfield migration of a legacy data center network replaced by a new EVPN fabric DC network using validated DC reference design.||Juniper Apstra solution implemented over the top of an existing (brownfield) EVPN fabric DC network infrastructure using validated DC reference design.|
|Migration Scenarios||Migrations to EVPN fabric DC network using Apstra supported multi-vendors (Juniper, Cisco, Arista) using validated DC reference design.||Migration from EVPN DC network (non-Apstra managed) to EVPN DC network managed by Apstra supported multi-vendor (Juniper to Juniper, Cisco to Cisco or Arista to Arista) using validated DC reference design.|
|Layer 2 Connectivity||Provides layer 2 connectivity between the legacy and the new data center network accommodating partial migration of workloads.||Existing network layer 2 connectivity remains in-place.|
|Layer 3 Connectivity||Provides layer 3 internet connectivity through the new network.||Existing network layer 3 connectivity remains in-place.|
|Apstra Supportability||New network must be Apstra supported devices running supported versions of the device Network Operating System (NOS).||Migration prerequisite requires existing in-place network to be Apstra supported devices running supported versions of the device Network Operating System (NOS).|
|Migration Steps||Includes Greenfield hardware deployment and incremental migration.||Migration can be executed all at once or in partial increments (For example, using split spine and leaf non-redundant network).|
Key Service Activities
As part of this service, the Juniper Professional Services consultant will advise on optimal phasing and grouping of the activities. Key activities performed by Professional Services consultant during deployment service include installing the Apstra software as one or a set of virtual machines (VMs) to connect and manage devices via agents installed on or off the devices. For data center reference designs, details such as single/dual-homing of servers, collapsed/3-stage/5-stage style of fabric, Ethernet VPN (EVPN)/IP fabric, and IPv4/IPv6 underlay can be specified as part of the template type and options. Once the fabric template is completed, it can be instantiated into blueprints, each representing an actual physical network. The allocation of the managed devices and network resources (“build phase”) is done within the blueprints. As the blueprint is built, Apstra automatically produces the necessary configuration for devices, providing an abstraction layer across vendors.
In cases of Freeform, Apstra presents an interactive canvas to visually design or model any arbitrary network topology to your specific deployment requirements. Blueprints created in the Freeform reference design consist of systems and links that you add and configure yourself, using Configuration Templates giving you complete control over your architecture.
Migrations are performed in steps –
- Building and preparing a new network.
- Moving all devices in each L2 domain, one at a time or in partial increments to the new fabric.
- Migrating the middleware (L4-L7) services: firewall, load balancer, and other components.
- Moving the L3 default gateway and related security policy.
With this strategy, migration phases can be organized in a flexible manner, allowing them to be aligned with priorities such as minimal downtime, lowest cost, or fastest completion. These phases can also be organized based on a variety of logical and physical parameters such as per application or per rack.
Apstra Automated Data Center Migration Service methodology follows a four-phase approach (Design, Build/Migrate, Deploy, and Operate) and is tightly integrated with the Juniper Project Management Methodology, which addresses both the project management and risk mitigation aspects of your project. While the methodology identifies the standard phases and types of activities within each phase, the specific activities to be included in an engagement are defined specifically for every customer. Similarly, the specific deployment tools and resource requirements are identified for each customer situation.
