25、eorge Glass argues that there is a point at which functions can become so granular as to be impractical or unmanageable.Initially proponents of microservices thought they would need to decompose systems and processes down to their most atomic or granular degree,but“I dont see operators or vendors mo

26、ving in that direction,”says Glass.Rather,TM Forum Open APIs are structured to allow for granularity in functionality,while exposing less complexity via the APIs.“I might expose an API thats around appointment management and there are microservices under it for move,change,cancel appointment,and oth

27、er functions.But no one would buy or consume a change appointment microservice on its own,so we have not gone to that level of granularity.”Glass adds:“Granularity tends to be collections of microservices that make sense and align with Open APIs.”of CSPs have fully committed to cloud-native IT for a

28、ll workloads33%TM Forum,20228inform.tmforum.orgMicroservices everywhereThe main reason CSPs are facing questions relating to functional granularity,architecture and scale is because they are adopting microservices across all areas of their businesses at once.Following are some of the parts of the bu

29、siness where CSPs are driving microservices adoption either overtly or inherently:Legacy OSS/BSS reconciliation here microservices give CSPs a new opportunity to access the valuable data stored in and managed well by their legacy systems,like billing and customer relationship management(CRM),without

30、 disrupting performance and while migrating away from them.“Ive seen this behavior used a lot by our members to manage transformation in a controlled manner,”says Glass.“They use Open APIs connected to microservices to get access to legacy data without having to plumb into the legacy applications or

31、 move all the data out,then they can move it in a controlled manner over time.”New software-as-a-service(SaaS)adoption the commercial model by which CSPs procure software is changing,moving away from long-term fees for licensing,maintenance and customization of monolithic applications toward cloud-n

32、ative and even SaaS applications.Increasingly these are multi-tenant,single code stream,no-code or low-code configurable and running in public clouds.In our recent report,How Liberty Latin America revamped to cloud BSS,we looked at how the company is eliminating software customization entirely in fa

33、vor of cloud-native technology and methodology.Rollout of 5G standalone core microservices are at the center of the 5G standalone core specification.“In this new architecture,each network function(NF)offers one or more services to other NFs via APIs,”says Robi Axiatas Akram.“Each NF is formed by a c

34、ombination of small pieces of software code,which are microservices.”Microservices allow reuse of 5G NFs,which simplifies implementation and enables independent lifecycle management.That way,“upgrades and new functionalities can be deployed with zero impact on running services,”he explains.In the ne

35、xt section,we take a closer look at how some CSPs are using microservices.Read the report:microservices in actionsection 29inform.tmforum.orgThere is no shortage of large-scale use cases for microservices since natively digital companies like Netflix and Amazon run their businesses on them.Tangible

36、microservices use cases abound among CSPs as well and can be found across operations,customer experience,services and networks.This section provides some examples from Hong Kongs Chunghwa Telecom,Indias Reliance Jio,DISH Wireless in the US and an unnamed service provider in the Asia-Pacific region.C

37、hunghwa Telecom automates operationsOne of the most common CSP use cases for microservices is reconciliation of legacy systems,typically in the context of digital transformation.Chunghwa Telecom provides the classic example of an operator launching an initiative to automate operations through OSS/BS

38、S reconciliation.Chunghwa Telecom is using TM Forums ODA as a design guide for operations automation as well as a blueprint for introducing an open ecosystem approach to delivering services to customers.Using the ODA,the company mapped,modelled and transformed 26 OSS/BSS stacks into just 11 ODA-base

39、d components and six sets of Open APIs.These support more than 6 million network resources with more than 1.2 billion automated service provisioning and network diagnostic events per year.Chunghwa has realized substantial benefits from its cloud transformation.Service launch time has dropped from fo

41、 Statista,the number of IoT devices worldwide is forecast to nearly triple from 9.7 billion in 2020 to more than 29 billion in 2030,and research firm IDC predicts double-digit growth in enterprises spending on IoT in most regions of the globe.Indias Jio is responding with automation to make it easie

43、hich can appeal to any market segment including resellers and channel partners.Jio designed its IoT platform using the ODA as a reference model,which provides a clearly defined model for CSPs to follow when,for example,designing portals with substantial user-driven automation.Jios IoT platform also

66、rm.tmforum.orgexplains the hyperscale product manager.This means that IT software engineers will be working with network engineers in CSPs NOCs,and in some cases it might mean retraining or upskilling network engineers with software skills.However,as automation of networks and operations progresses,

67、the idea is for the NOC to become obsolete.Marc Rouanne,Chief Network Officer at DISH Wireless,explains:“My dream is to have no man-machine interface.No alarms,no reports.No NOC,no nothing.”In this vision,the network operations center ceases to exist because an alarm is just an event,a trigger for a

68、n orchestrator to act.What about scale?Whether microservices architectures can scale is a concern expressed by all the CSP architects interviewed for this report.The big question is how the increasing dependence on clouds and microservices will impact the network-service-customer models and practice

69、s used for network and service management.TM Forums Glass says CSPs need to“work out many steps in the background about where the resources are,who has access to them,who has permission to use them,and how you prioritize them when demand exceeds supply.So,for example,when they are busy how do you ma

70、nage competing requests from network microservices?”Here,the focus is not on the cloud IT infrastructure,but rather on how customers are impacted by the collective performance of the technology stack.Catalyst program helps Axiata build a new multi-cloud orchestrator Axiata Group used learnings from

71、a multi-phased TM Forum Catalyst proof of concept to address the challenges of multi-cloud orchestration and develop a single monitoring and DevOps screen for operations teams.In 2019 and 2021,two Axiata operating companies,Robi in Bangladesh and Dialog in Sri Lanka,championed the projects,which inc

76、ucture and clouds are just one piece,but they represent a critical dependency that must be managed from a service management perspective.Glass suggests that network,service or operations functions should not be defined too granularly in independent microservices because“you end up having to build al

77、l the logic of these complex services.”Increased granularity can breed complexity,making it harder to scale,manage and diagnose problems with networks and services,which is part of what makes CSPs adoption of microservices across all domains so complex.But some operators and their hyperscale partner

78、s are already anticipating the next step for microservices.Serverless computingMicroservices technology is evolving to find new ways to use componentization more efficiently at greater scale.Serverless computing architecture,for example,takes much of the overhead out of microservices deployments.Wit

79、h this approach,users need not“deploy,maintain and operate the servers on which you run these microservices,”says the hyperscale product manager.He adds that because the service offers elasticity,“you dont have to predict and run large fleets”of servers to scale,which in turn lowers costs.Some opera

80、tors are examining how to use serverless computing as an option for mobile core architecture.“Scaling is not a problem with serverless since its cloud managed,”says Harpreet Singh,Wireless Product Team Manager at TELUS.“With serverless we kind of outsource container management and scalability,so we

81、focus on functions and compute.”He adds that this not only helps to eliminate or solve some of the scalability concerns with large,message-volume heavy microservices architectures,but it also enables far faster development because developers are not tasked with scale and container management.Other a

82、rchitects share concerns,however,that even in an IT infrastructure setting that might scale elegantly,the dependencies between network and service commitments and IT infrastructure performance must be observable and able to be reconstructed after the fact.These are the kinds of challenges many archi

88、mitments to customers,they need to create a single pane of glass,or unified vision of IT infrastructure in the NOC,for operations teams the way that Axiata Group has done.But operators should also keep in mind that as they introduce more automation,the NOC will become less important over time,as exp

89、lained by DISHs Rouanne earlier in this report.Add multidisciplinary skillsAs CSPs adopt microservices,they also are using more analytics,decisioning and automation.This necessitates that operators upskill,reskill or recruit people with experience in data analysis,cloud computing,security,DevOps and

90、 other cloud-native methodologies,machine learning and AI.This combination of skills is necessary to manage the real-time nature of cloud-native environments.19inform.tmforum.orgMeasure the benefitsMany CSPs that have adopted microservices are realizing double-digit percentage improvements in key pe
