It is tempting to date cloud computing from the launch of Amazon S3 in 2006 and the rise of infrastructure as a service (IaaS) that followed. That was certainly the moment the market changed in a visible, irreversible way. But the truth is that cloud began earlier, in the 1990s, when software as a service (SaaS), application hosting, managed services providers, and various forms of remote subscription computing started to reshape how enterprises thought about owning and operating technology. Even then, the core value proposition was familiar: Let someone else run the infrastructure, abstract the complexity, deliver capability as a service, and allow the business to consume only what it needs.

What AWS changed was the scale, accessibility, and precision of the execution. Amazon turned infrastructure into a programmable utility. It made compute and storage available in ways that were elastic, self-service, API-driven, and globally reachable. That was the breakthrough. Enterprises had outsourced pieces of technology before, but now they could rent raw infrastructure with unprecedented speed and flexibility. The launch of Amazon S3 was especially important because it provided a durable, scalable storage foundation that became one of the building blocks for modern digital business.

AWS changed everything

Technology markets are rarely transformed by the first company to think of an idea. They are transformed by the first company to make that idea operationally real, economically viable, and broadly consumable. AWS did exactly that. It built a model for infrastructure as a service that allowed enterprises, startups, and eventually governments to rethink the entire life cycle of IT delivery.

Looking back from 2026, it is difficult to remember how radical this concept once seemed. At the time, many enterprise leaders considered public cloud too risky, too immature, too uncontrolled, or simply too foreign for conventional IT governance. There were concerns about security, compliance, vendor dependency, performance, data residency, and reliability. Many of those concerns were valid. Early cloud adoption often ran ahead of cloud maturity, and many organizations discovered that moving quickly did not always mean moving wisely.

Still, the economics of agility overwhelmed the inertia of the old model. Provisioning that once took months could be done in minutes. Capital expenditure gave way, at least in part, to operating expenditure. Experimental workloads became easier to justify. Digital businesses could scale without building data centers first. AWS led that transition, and the rest of the industry followed, including competitors that helped mature the market.

Cloud’s strengths and liabilities

If the first decade of cloud was about acceleration, the second decade was about correction. Enterprises learned that cloud was not automatically cheaper, not automatically simpler, and not automatically better. It was better when used with discipline. It was more cost-effective when architected intelligently. It was more resilient when governance, operations, and security were designed into the system rather than added later.

This is when the industry grew up. We learned about cloud financial management because too many organizations assumed elasticity would control cost, only to discover that unused resources, poor workload placement, and fragmented accountability could drive spending far beyond expectations. We learned that public cloud could provide extraordinary innovation and reach, but also that not every workload belongs there. Latency, sovereignty, compliance constraints, legacy integration challenges, and predictable high-volume workloads all forced a more nuanced view.

We also learned about concentration risk. As enterprises standardized on a small number of hyperscalers, questions emerged around resilience, lock-in, and strategic dependency. The answer was never simplistic multicloud posturing for its own sake. It was architectural realism. Use the public cloud where it creates a clear advantage. Keep options open where business risk requires it. Understand portability, but do not romanticize it. In other words, cloud became less ideological and more practical.

Cloud is now an assumption

Perhaps the most important shift of all is that we no longer debate whether cloud is real or whether enterprises should use it. That argument is over. Cloud is baked into the cake. It is part of enterprise operating reality. The modern enterprise assumes on-demand infrastructure, platform services, automation pipelines, managed databases, identity fabrics, observability stacks, and globally distributed application delivery. Even when workloads remain on-premises or at the edge, they are often built, governed, or operated with cloud-native thinking.

This is maturity. Cloud is not a project or a trend. It is not even a strategy by itself. It is an enabling model that now underpins enterprise strategy. Businesses no longer ask whether to adopt cloud in the abstract. They ask how much cloud, which cloud services, under what governance model, at what cost profile, and in support of which business outcomes.

That may sound less exciting than the early days of disruption, but it is actually the mark of success. The most powerful technologies eventually disappear into standard practice. Electricity, networking, virtualization, and mobile platforms all went through this process. Cloud has done the same.

How cloud supports the AI race

As enterprises move aggressively into AI, cloud has entered another pivotal phase. AI is not replacing cloud. It is intensifying the importance of cloud while also changing how value is measured. Training, tuning, deploying, and governing AI systems require immense computational scale, specialized infrastructure, distributed data access, and operational consistency. Public cloud providers are well positioned to offer those capabilities, particularly with GPUs, AI platforms, managed model services, and data integration tools.

But this is not a repeat of the early cloud era. Enterprises are more sober now. They know the importance of cost, latency, and data gravity. They know that governance and accountability matter more in AI than perhaps anywhere else in modern IT. The role of cloud in the AI race is therefore foundational, but not absolute. Some AI workloads will run in public cloud. Some will be distributed across edge computing environments. Some will remain in private environments for reasons of sovereignty, economics, or control. The key is not to force a universal answer. The key is to create an architecture that aligns AI ambitions with operational reality.

Cloud should play the role it has gradually earned: not as a religion, but as a strategic utility. For AI, the cloud is where many enterprises will source scale, experimentation speed, global reach, and managed innovation. The winning organizations understand where cloud creates leverage and where other operating models make more sense.

Changing how enterprises think

The real story of the past 20 years is not just that AWS launched S3 and helped popularize infrastructure as a service. It is that cloud changed enterprise behavior. It normalized service consumption over asset ownership. It moved architecture toward abstraction, automation, and modularity. It forced IT organizations to broker capability rather than build everything from scratch. It redefined speed as a core competitive requirement.

And now, as AI becomes the next forcing function, cloud stands less as a novelty and more as the platform on which the next era will be built. That is a remarkable outcome for something that, in many ways, started with the old idea that computing could be delivered remotely on a subscription basis. We have been heading here for longer than many people realize. In the past two decades, led in large measure by AWS and the broader hyperscale movement it accelerated, cloud has evolved from a gamble to an indispensable foundation.

Hard to believe? Yes. But also inevitable in retrospect.

For many developers, the hard part of building an AI application isn’t the model anymore. It’s keeping the application’s knowledge current.

Retrieval-augmented generation (RAG) has become a popular technique for grounding AI applications in enterprise data, but it also introduces a steady stream of operational work, including tasks such as updating embeddings and indexes, synchronizing data sources, and tuning retrieval performance.

AWS is seeking to remove much of that burden with Bedrock Managed Knowledge Base, a new managed service that automates the retrieval layer behind enterprise AI applications.

“By default, the service automatically selects and manages a default embeddings model, re-ranker model, and foundational model on your behalf, so you can get up to speed quickly without needing to pick or maintain one yourself,” Daniel Abib, senior solutions architect at AWS, wrote in a blog post.

In order to help maintain data pipelines without building and managing custom integrations, the service also comes with six native connectors for enterprise data sources, including Amazon S3, SharePoint, Confluence, Google Drive, OneDrive, and web content, Abib wrote.

Managed RAG could boost developer productivity

For developer teams, the ability to automatically manage infrastructure could provide an immediate boost in productivity, according to Pareekh Jain, principal analyst at Pareekh Consulting.

“Enterprises spend significant time building data connectors, managing document ingestion and indexing, tuning retrieval quality, enforcing access controls, and maintaining vector databases, often making the RAG infrastructure more complex than the AI application itself. With this, developers can now focus on building the application,” Jain said.

“That should accelerate deployment timelines and reduce maintenance costs while enabling teams to focus on business outcomes,” Jain added.

Beyond reducing infrastructure management overhead, Managed Knowledge Base also targets retrieval accuracy. The service, according to Abib, also comes with features, such as Smart Parsing and Agentic Retriever, which are aimed at helping improve accuracy across different content types and sources, which is often an issue with RAG pipelines and queries spanning multiple repositories.

Improved retrieval quality could prove particularly important for organizations looking to move AI projects from experimentation to production, according to Jain.

“This is a common challenge across enterprises because business data is scattered across multiple systems. As organizations move from AI pilots to production, retrieval quality becomes critical for user trust, making RAG infrastructure a major bottleneck that often delays deployments,” Jain said.

AWS is also positioning Managed Knowledge Base as a building block for agentic applications, which, Jain said, can place even greater demands on enterprise knowledge and retrieval systems.

The service, according to the hyperscaler, integrates with Bedrock AgentCore, reducing the amount of code and configuration required to connect enterprise knowledge sources to AI agents while providing built-in monitoring, evaluation, and access management capabilities.

Taking aim at RAG stacks?

That integrated approach could also have implications for the broader RAG tooling ecosystem, Jain said.

“Managed services such as Bedrock Managed Knowledge Base could reduce demand for standalone RAG orchestration and retrieval frameworks, including tools such as LangChain and LlamaIndex, as well as some custom combinations of vector databases, ingestion pipelines, and retrieval services,” Jain noted.

However, Jain cautioned that the convenience of an integrated approach comes with tradeoffs, potentially increasing customer dependence on a single cloud provider and limiting flexibility in how AI infrastructure is assembled and managed.

Amazon Bedrock Managed Knowledge Base is currently available across North Virginia, Oregon, Sydney, Tokyo, Dublin, Frankfurt, London, and AWS GovCloud (US-West) Regions.

The service follows a usage-based pricing model, with charges tied to the volume of indexed data stored and retrieval requests processed.

Licensing can be complicated, particularly when enterprises are forced to double-pay because the software they already own is only licensed for a specific environment, and moving it requires a whole different licensing model. Without proper portability rights, they need to make additional financial investments to run the same workloads in a different home.

AWS says its new Bring Your Own Media (BYOM) service eliminates this duplication. Customers can now reuse their existing Microsoft SQL Server media and licenses on Amazon Relational Database Service (RDS) with no additional licensing fees.

This means enterprises no longer have to justify workload migrations to the cloud against existing licensing commitments and infrastructure investments, AWS said.

“What used to be a licensing barrier between operational SQL Server data and agentic AI is now gone,” AWS data engineer Srikanth Katakam and product marketing manager Colleen Betik wrote in a blog post announcing the service.

Avoiding the double-licensing problem

To drive true value, agentic AI apps must have access to elastic GPU capacity as well as direct, low-latency access to the data they need to reason and make decisions. But, AWS argued, that can be difficult in self-managed data centers and on premises infrastructure with limited access to agentic AI cloud-native services. But a lot of enterprise data lives in Microsoft SQL Server, and until now customers have had to pay for a second license to use a fully managed cloud service like RDS.

Now, with BYOM on Amazon RDS for SQL Server, enterprises can reuse their existing SQL Server Enterprise Edition or Standard Edition licenses through a “lift-and-shift” model. This brings their data into a fully-managed environment.

According to the licensing distribution terms, enterprises must provide their licensed SQL Server Release to Manufacturing (RTM) media to Amazon RDS. They can then upload that media to Amazon S3 and launch BYOM instances. Enterprises must configure AWS License Manager to perform automatic instance tracking.

From there, RDS automates patching, backups, high availability, and monitoring, while providing direct access to agentic AI and analytics services native to AWS. The platform also reports vCPU usage to provide visibility into SQL Server license usage, Katakam and Betik wrote.

“You do not need to choose between protecting your SQL Server licensing investments and giving your data a path to the AWS analytics and agentic AI services redefining what’s possible in the cloud,” they said. 

It’s important to note that this service is only available to enterprises with Microsoft Software Assurance (SA), an add-on which supports mobility and rehosting of existing licenses. Enterprises must verify that their SQL Server licenses comply with Microsoft’s licensing agreement, and that they have a SQL Server License (Standard or Enterprise) with SA. They also must submit a License Mobility Verification Form to Microsoft; it, in turn, will notify AWS once verification is complete.

AWS emphasized that enterprises remain responsible for compliance; it does not block operations if license limits are exceeded.

More control over workloads, loosening Microsoft’s grip

The advantage of this service, explained Mike Leone, principal analyst at Moor Insights & Strategy, is that enterprises can get a Microsoft SQL Server workload onto a managed AWS service without rewriting it for Aurora or paying for the license twice. This means they can modernize on their own schedule rather than being forced into rewrites before they’re ready.

“For a lot of shops, that control over timing is worth more than the license saving itself,” Leone said.

This also loosens Microsoft’s grip on enterprise workloads, because organizations finally have somewhere else to run SQL Server using licenses they already own, he noted. Realistically, their dependency shifts to AWS rather than disappearing entirely, as their data ends up living next to AWS’s AI services.

“For a lot of teams, that’s a trade they’re glad to make for the managed infrastructure and the AI tooling they get in return,” Leone said.

Yaz Palanichamy, a senior advisory analyst at Info-Tech Research Group, also pointed to significant improvements stemming from the migration. Notably, it allows organizations to transition away from static, linear, or reactive storage capabilities towards more dynamically intelligent environments.

“The key is to balance the unification of transactional data towards managed AI and machine learning pipelines,” he said.

Enterprises take on new responsibilities

The catch? Leone noted that enterprises now own the task of licensing compliance. Staying current on SA, the Microsoft maintenance contract that makes any of this legal, and the license mobility rules, “become your headache instead of something baked into the bill,” he said.

Furthermore, he added, lift-and-shift has a way of turning into “lift-and-forget” when enterprises move SQL Server as-is and never actually modernize, “so you end up carrying all the old baggage onto a shinier platform.”

Palanichamy also pointed to skyrocketing AWS costs, since operationalizing AI agents requires a considerable amount of data ingestion and querying. This can potentially be cost prohibitive on RDS for SQL Server.

“One aspect to consider would be the relative time to production value, so that enterprises can better handle the management of volatile AI workloads,” he said.

Just one challenge in the AI race

Although AWS frames licensing complexity as a roadblock to agentic AI, analysts say it’s really just one piece of the puzzle.

Organizations are not in an AI-ready state due to a number of factors, Palanichamy noted. This could be total cost of ownership (TCO)-related, a lack of appropriate acceptable use policies (AUPs), or concerns around security and compliance.

If and when enterprises are ready to adopt AI, they must perform thorough needs analysis/process optimization benchmarking exercises to determine what workflows could benefit from the technology, he said, and, conversely, flag workflows where AI could prove “an impediment or potential disservice.”

Leone also pointed out that moving SQL Server onto RDS doesn’t “magically make your data agent-ready,” nor does it make it smarter. The data proximity and managed plumbing are what actually support agents. Sitting data next to Bedrock and the rest of AWS’s AI services means builders “stop wasting time shipping the data around or building one-off integrations every time an agent needs it.”

Ultimately, though, licensing isn’t the real issue when it comes to AI; it’s more of a migration problem. The real roadblocks are messy data, questionable governance, and teams that aren’t ready to run it in production, and, Leone said, “no change to a license bill touches a single one of them.”
