It explains how PostgreSQL, MongoDB, and Valkey can serve as systems of record for stateful AI applications, supporting persistent context, recovery in multi-stage workflows, and access to organization-specific data. ### Source excerpt As AI moves from experimental chat interfaces to production-grade agents, the need for a foundational memory layer to transform these AI-powered tasks into stateful models is apparent. The absence of a robust memory layer causes agents to lose vital statefulness, leading to: Inability to maintain long-term recall. Without persistent memory to track context across sessions, an agent might recognize specific user preferences in January but fail to apply that data months later, requiring the user to repeat the entire briefing. Vulnerability in multi-stage workflows. Lacking durable execution, there is no "save point" for recovery; consequently, a simple network interruption forces complex agentic processes, such as gathering diagnostic data via multiple tool calls, to restart entirely rather than resume from the point of failure. Disconnect from business-specific realities. If an agent cannot access private internal records or real-time operational data, it relies on general training data and guesswork, often confidently fabricating generic policies or specifications that are factually inaccurate for your organization. DigitalOcean is constantly evolving to meet this challenge, and we've entered the era of the inference cloud: A full-stack cloud platform purpose-built to run AI in production. With Gradient™AI Platform providing the specialized compute for AI applications, DigitalOcean Managed Databases serves as the foundational memory layer. Offerings from PostgreSQL, MongoDB, and Valkey function as the system of record for today's stateful AI applications, particularly so when they're connected to the DigitalOcean Agentic Inference Cloud. What is the inference cloud? The need for an inference cloud stems from a fundamental shift in how AI is being built, deployed, and used in 2026. For years, the industry's focus was on training or the capital-intensive process of building a model. But now developers are shifting to running that pre-trained model in a live product. T ## Why Decoupling Databases from Kubernetes Clusters Improves Reliability DevFeed: [Why Decoupling Databases from Kubernetes Clusters Improves Reliability]() Original publisher: [Read original article]() Author: Zach Peirce Published: 2026-02-10T14:00:00Z Content type: article Language: en Sources: [DigitalOcean]() Topics: [Kubernetes](), [Database](), [Databases](), [Cloud](), [Inference](), [Persistence](), [Artificial Intelligence](), [Digital Ocean]() Tags: [ai](), [cloud](), [cloud-native](), [databases](), [digitalocean](), [inference](), [kubernetes](), [kubernetes-clusters](), [latency](), [mongodb](), [opensearch](), [persistence](), [postgresql](), [tech-stack-advice](), [valkey]() ### AI overview The article argues that stateful databases should generally be managed outside ephemeral Kubernetes clusters. It describes Kubernetes as the execution layer and managed databases as a stable memory layer for inference-oriented applications, citing resource contention and latency as key concerns. ### Source excerpt Kubernetes has won the cloud-native war for a reason: it's one of, if not the most powerful tool we have for scaling applications and ensuring they stay up when unexpected things happen. But as we move into the era of the Inference Cloud, we've fallen into a trap. We've become so enamored with "everything-as-code" that we're forcing our most sensitive data inside the cluster. At DigitalOcean, we see thousands of enterprises building on DigitalOcean Kubernetes (DOKS). The most successful ones have realized a counter-intuitive truth: To manage your Kubernetes clusters effectively, you must stop managing your databases inside them. Just because you can run your database in a container, doesn't mean you should. The Inference Cloud demands a new standard In 2026, the stakes have changed. We're no longer just scaling web services, we're scaling data-intensive inference workflows. AI-driven applications require massive bursts of compute and near-instant access to vector data, metadata, and user context. When your database competes for resources inside your Kubernetes cluster, your inference latency suffers. That's why DigitalOcean Managed Kubernetes and DigitalOcean Managed Databases (fully-managed PostgreSQL, MySQL, MongoDB, Caching for Valkey, and OpenSearch database services) are the two essential pillars of our inference cloud, working to solve this issue. Managed Kubernetes acts as the execution layer, while Managed Databases acts as the memory layer. Together, they deliver an attach-architecture that pairs high-performance compute with a stable, external data foundation. We will discuss this in more detail. The "stateful" friction Kubernetes was designed to be stateless-to kill, move, and restart pods at a moment's notice. For databases, this model is far from ideal. Databases are inherently stateful, and running systems like PostgreSQL or MongoDB inside a Kubernetes cluster introduces friction between the two, what is commonly referred to as the operational tax.

It describes compatibility problems caused by runtime, package, and schema changes, including cache misses and thundering-herd effects during migrations. ### Source excerpt In this part of the Scaling Nextdoor's Datastores blog series, we'll explore how the Core-Services team at Nextdoor serializes database data for caching while ensuring forward and backward compatibility between the cache and application code. In part 1 of this series we discussed how ORMs, object-relational mapping frameworks, help abstract away database specific schemas and queries from application code. Developers simply utilize objects in their application's language to access database data. Here's a simple example of using Python's Django ORM to define a model: from django.db import models class Users(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) The associated SQL create table would look like: CREATE TABLE users ( "id" bigint NOT NULL PRIMARY KEY GENERATED BY DEFAULT AS IDENTITY, "first_name" varchar(30) NOT NULL, "last_name" varchar(30) NOT NULL ); Developers would then access database data like this: user_id = 123 user = User.objects.get(id=user_id) print(user.first_name)Object Byte Serialization for Caching An issue arises when adding a look-aside cache such as Redis/Valkey to an application: How do you store what you got from the database in the cache? A common solution to caching complex objects, such as those from ORMs, is object byte serialization. This process converts language objects into bytes before storing them in the cache. When reading from the cache the process is done in reverse where the byte data is turned into language objects. For instance in Python this is often done with the pickle package. The interaction between the application, database, and the cache looks like this: Look-Aside Cacheimport pickle # Try getting from cache ('None' if not in cache) user_bytes = cache.get("user_123") if user_bytes is not None: # Read bytes using pickle user = pickle.loads(user_bytes) else: # Fetch from database user = User.objects.get(id=123) # Convert to bytes user_bytes = pickle.dumps(user) # Sto ## Chainguard Images April 2024: Secure, reliable, feature-rich DevFeed: [Chainguard Images April 2024: Secure, reliable, feature-rich]() Original publisher: [Read original article]() Published: 2024-05-09T00:00:00Z Content type: release Language: en Sources: [Chainguard: Unchained]() Topics: [chainguard images](), [supply-chain-security](), [container images](), [Security](), [Open Source](), [FFmpeg (Fast Forward Moving Picture Experts Group)](), [MATLAB](), [Kubernetes]() Tags: [chainguard](), [chainguard-images](), [compliance](), [container-images](), [ffmpeg](), [fips](), [fips-compliance](), [harbor](), [kubernetes](), [open-source](), [release](), [rstudio](), [secure-container-image](), [security](), [software-supply-chain](), [software-supply-chain-security](), [tesseract](), [valkey](), [vulnerability]() ### AI overview Chainguard announces approximately 60 new Chainguard Images in its April 2024 release.
