21、nsight into how organizations approach application modernization.Here are the highlights:Companies plan to modernize 78%of their custom applications within the next year.Application modernization describes many different initiatives,including containerizing workloads,automating or reducing operation

22、s,and bringing workloads into the cloud.Scalability and reliability are the two most cited reasons for both why companies modernize and how they plan to measure modernization success.Resistance to change and time constraints are the most common barriers to getting started with modernization.Cost and

23、 budget constraints become the biggest barrier during the modernization process.External partners will play key roles in 70%of application modernization journeys,either leading in-house teams or directly modernizing applications.Organizations expect to use a variety of modernization strategies in ne

24、ar-equal proportions.But when you consider that 90%of those who plan to refactor applications will replatform them as a first step,replatforming becomes the strategy that will be the most used.Companies plan to modernize core back-end applications first.More companies expect to have artificial intel

35、d be quick or straightforward.Even so,customers continue to bring up these timelines in conversations with increasing frequency.The pandemic clearly showed how critical innovation and agility are to business success,and modernization is at the core of these initiatives.Actual modernization timelines

36、 will depend on many factors,including available budget,the type of application,how it was created originally,how it is deployed,and the number and complexity of dependencies it has.The level of modernization needed and the size of an organizations application portfolio will also impact timelines.Se

37、veral things can help organizations achieve their goals faster.Deploying a modern,cloud-native IT architecture prior to application modernization,following a proven methodology,and using the right tools can simplify and speed the process.And,once you start modernizing your applications,you can apply

38、 learnings to optimize your techniques.For example,you can validate your modernization process and tools on one application and use the knowledge and experience youve gained to modernize other similar applications at scale.Finding 2:Modernization means several different thingsRespondents define appl

43、more on containerizing workloads and improving continuous integration/continuous deployment(CI/CD)than any other region.U.S.respondents selected using microservices in the cloud more often than U.K.or APAC organizations.And U.K.respondents chose bringing workloads to the cloud by a higher margin tha

49、 to understand the reasons that organizations are modernizing and how they plan to measure the success of their modernization efforts.As it happens,innovationrather than costwas key in both cases.Increasing reliability and scalability were cited as both top drivers and key success indicators for app

50、lication modernization.Decreasing costs was the number three driver and number four success indicator overall,with roughly the same emphasis as improving security.As reliability,scalability,and security are fundamental to innovation,these results show that companies are more focused on transforming

51、their services and business than on simply cutting costs.As before,there were significant regional differences.APAC respondents ranked improving security as high as increasing scalability and reliability in both cases,while decreasing costs was a considerably higher concern for U.S.and U.K.responden

52、ts.Improving customer experiences was also a much higher priority for APAC respondents,especially compared with U.S.respondents.Even so,each of the options in the survey are interconnected with others.For example,increased reliability,scalability,and security can support improved customer experience

53、s and employee productivity.As a result,the regional differences we see may say more about the roles of individual respondents rather than the overall goals of their organizations.ITDMs may focus on business-level outcomes,while developers and architects may rank more tactical actions higher.10Execu

64、.We asked respondents about two sets of challenges related to application modernization:barriers preventing them from getting started and obstacles that keep them from moving forward during the modernization process.Unsurprisingly,resistance to change,time constraints,and budget restrictionscommon c

65、hallenges for large IT projectswere cited as top barriers in both situations.Resistance to change was the top barrier to getting started(32%)and number two challenge during the modernization process(25%).Resistance to change often correlates with a lack of skills or resources related to new technolo

66、gies(20%and 17%,respectively),so training and skills development should also be prioritized with modernization efforts.Time constraintsthe number two barrier to getting started(28%)and progressing(tied with resistance to change at 25%)are often related to larger challenges in connecting and aligning

67、 teams within organizations.Each team involved needs to have time to work on modernization projects at the same time as the others:scheduling and orchestration are critical.Finally,budget constraints were the number three barrier to getting started(26%),but rose to number one during the modernizatio

68、n process(27%).Even so,the cost of continuing to maintain legacy applicationsincluding software and support contracts,the ability to find staff with the right skills,and lost opportunity costsoften far exceeds modernization costs.13Executive summaryAbout this reportKey findingsFinding 1:Application
