Embrace a Microservices Application Architecture

As AT&Ts VP of Domain 2.0 architecture writes one aspect of their Domain 2.0 strategy is a goal to embrace a Microservices Application Architecture.

One page 9 they describe how these envisage them fitting into the ECOMP architecture:

"The initial steps of the recipes include a homing and placement task using constraints specified in the requests. ‘Homing and Placement' are micro-services involving orchestration, inventory, and controllers responsible for infrastructure, network, and application. The goal is to allow algorithms to use real-time network data and determine the most efficient use of available infrastructure capacity."

This was a scenario industry expert Tom Nolle envisaged, and vendors like Ciena have re-engineered their telco platform offering accordingly.

This last point highlights how they will interface with the DCAE big data smart management framework.

"Analytic applications are developed by various organizations, however, they all run in the DCAE framework and are managed by the DCAE controller. These applications are micro-services developed by a broad community and adhere to ECOMP Framework standards."

Cloud Transformation - From Monolith to Microservices
These goals highlight how they face the same challenges that every organization faces who want to embrace Microservices: Creating new apps is relatively easy, factoring in your existing legacy applications is an entirely different, very difficult challenge - A shift from ‘Monolith to Microservices‘.

As AT&T describes:

"The BSS transformation to support the dynamic D2 environment is based on the following: Building blocks - BSS migration from monolithic systems to a platform building block architecture that can enable upstream User Experience (UX) changes in how products are sold, ordered, and billed."

These service elements lead us into the final aspect of the AT&T program, their anticipated Business Transformation.

Page 24 provides a complete overview of the departmental functions they expect to require some form of modernization to reflect this new platform capability, such as Sales, Marketing and Billing capabilities.

"D2-based Offer/Products will be designed, created, deployed and managed in near real-time, rather than requiring software development cycles. ECOMP is the framework that provides service creation and operational management of D2 which enables significant reductions in the time and cost required to develop, deploy, operate and retire AT&Ts products, services and networks.

The Business Support Systems which care for such capabilities as sales, ordering, and billing will interact with ECOMP in the D2 architecture, and those systems will need to pivot to this new paradigm."

The dream is universal: heuristic driven, global business operations without interruption so that nobody has to wake up at 4am to solve a problem. Building upon Nutanix Acropolis software defined storage, virtualization, and networking platform, Mark will demonstrate business lifecycle automation with freedom of choice and consumption models. Hybrid cloud applications and operations are controllable by the Nutanix Prism control plane with Calm automation, which can weave together the following: database as a service with Era, micro segmentation with Flow, event driven lifecycle operations with Epoch monitoring, and both financial and cloud governance with Beam. Combined together, the Nutanix Enterprise Cloud OS democratizes and accelerates every aspect of your business with simplicity, security, and scalability.
At CloudEXPO Silicon Valley, June 24-26, 2019, Digital Transformation (DX) is a major focus with expanded DevOpsSUMMIT and FinTechEXPO programs within the DXWorldEXPO agenda. Successful transformation requires a laser focus on being data-driven and on using all the tools available that enable transformation if they plan to survive over the long term. A total of 88% of Fortune 500 companies from a generation ago are now out of business. Only 12% still survive. Similar percentages are found throughout enterprises of all sizes.
ScaleMP is the leader in virtualization for in-memory high-end computing, providing higher performance and lower total cost of ownership as compared with traditional shared-memory systems. The company's innovative Versatile SMP (vSMP) architecture aggregates multiple x86 systems into a single virtual x86 system, delivering an industry-standard, high-end shared-memory computer. Using software to replace custom hardware and components, ScaleMP offers a new, revolutionary computing paradigm. vSMP Foundation is a software-only solution that reduces overall system (CAPEX) and management complexities (OPEX) costs. vSMP Foundation aggregates up to 128 x86 systems to create a single system with up to 32,768 cpus and up to 2 PB of shared memory.

Skeuomorphism usually means retaining existing design cues in something new that doesn’t actually need them. However, the concept of skeuomorphism can be thought of as relating more broadly to applying existing patterns to new technologies that, in fact, cry out for new approaches. In his session at DevOps Summit, Gordon Haff, Senior Cloud Strategy Marketing and Evangelism Manager at Red Hat, discussed why containers should be paired with new architectural practices such as microservices rather than mimicking legacy server virtualization workflows and architectures.
