Red Hat’s Vision for an Open Source AI Future -The world of artificial intelligence (AI) is evolving at a lightning pace. As with any transformative technology, one question stands out: what’s the best way to shape its future? At Red Hat, we believe the answer is clear—the future of AI is open source

This isn’t just a philosophical stance; it’s a commitment to unlocking AI’s full potential by making it accessible, collaborative, and community-driven. Open source has consistently driven innovation in the technology world, from Linux and Kubernetes to OpenStack. These projects demonstrate how collaboration and transparency fuel discovery, experimentation, and democratized access to groundbreaking tools. AI, too, can benefit from this model.

Why Open Source Matters in AI

In a field where trust, security, and explainability are critical, AI must be open and inclusive. Red Hat is championing open source AI innovation to ensure its development remains a shared effort—accessible to everyone, not just organizations with deep pockets.

Through strategic investments, collaborations, and community-driven solutions, Red Hat is laying the groundwork for a future where AI workloads can run wherever they’re needed. Our recent agreement to acquire Neural Magic marks a significant step toward achieving this vision – Amrita Technologies.

Building the Future of AI on Three Pillars

1.Building the Future of AI on Three Pillars

AI isn’t just about massive, resource-hungry models. The focus is shifting toward smaller, specialized models that deliver high performance with greater efficiency.

For example, IBM Granite 3.0, an open-source family of models licensed under Apache 2.0, demonstrates how smaller models (1–8 billion parameters) can run efficiently on a variety of hardware, from laptops to GPUs. Such accessibility fosters innovation and adoption, much like Linux did for enterprise computing.

Optimization techniques like sparsification and quantization further enhance these models by reducing size and computational demands while maintaining accuracy. These approaches make it possible to run AI workloads on diverse hardware, reducing costs and enabling faster inference. Neural Magic’s expertise in optimizing AI for GPU and CPU hardware will further strengthen our ability to bring this efficiency to AI.

2. Training Unlocks Business Advantage

While pre-trained models are powerful, they often lack understanding of a business’s specific processes or proprietary data. Customizing models to integrate unique business knowledge is essential to unlocking their true value.

To make this easier, Red Hat and IBM launched Instruct Lab, an open source project designed to simplify fine-tuning of large language models (LLMs). Instruct Lab lowers barriers to entry, allowing businesses to train models without requiring deep data science expertise. This initiative enables organizations to adapt AI for their unique needs while controlling costs and complexity

3. Choice Unlocks Innovation

AI must work seamlessly across diverse environments, whether in corporate datacenters, the cloud, or at the edge. Flexible deployment options allow organizations to train models where their data resides and run them wherever makes sense for their use cases.

Just as Red Hat Enterprise Linux (RHEL) allowed software to run on any CPU without modification, our goal is to ensure AI models trained with RHEL AI can run on any GPU or infrastructure. By combining flexible hardware support, smaller models, and simplified training, Red Hat enables innovation across the AI lifecycle.

With Red Hat OpenShift AI, we bring together model customization, inference, monitoring, and lifecycle management. Neural Magic’s vision of efficient AI on hybrid platforms aligns perfectly with our mission to deliver consistent and scalable solutions – Amrita Technologies.

Welcoming Neural Magic to Red Hat

Neural Magic’s story is rooted in making AI more accessible. Co-founded by MIT researchers Nir Shavit and Alex Matveev, the company specializes in optimization techniques like pruning and quantization. Initially focused on enabling AI to run efficiently on CPUs, Neural Magic has since expanded its expertise to GPUs and generative AI, aligning with Red Hat’s goal of democratizing AI.

The cultural alignment between Neural Magic and Red Hat is striking. Just as Neural Magic strives to make AI more efficient and accessible, Red Hat’s Instruct Lab team works to simplify model training for enterprise adoption. Together, we’re poised to drive breakthroughs in AI innovation.

Open Source: Unlocking AI’s Potential

At Ruddy Cap, we accept that openness opens the world’s potential. By building AI on a establishment of open source standards, we can democratize get to, quicken advancement, and guarantee AI benefits everyone. With Neural Enchantment joining Ruddy Cap, we’re energized to increase our mission of conveying open source AI arrangements that enable businesses and communities to flourish in the AI period. Together, we’re forming a future where AI is open, comprehensive, and transformative – Amrita Technologies.

Simply about Linux Security

Linux is often praised as one of the best operating systems in terms of security due to several key factors that make it inherently secure and resilient against many types of attacks. Here's why:

1. Open-Source Nature

Transparency: Linux is open-source, meaning its source code is publicly available for review. This transparency allows anyone (including security experts) to examine the code for vulnerabilities, report bugs, and contribute fixes. This collaborative approach leads to faster identification and patching of security issues compared to proprietary systems.

Community and Auditing: Since many users and organizations contribute to Linux's development, any vulnerabilities discovered are often addressed quickly.

2. User Privileges and Access Control

Least Privilege Principle: In Linux, by default, users do not have administrative (root) access to the system. Administrative rights are required to make significant system changes, reducing the risk of malware or attackers exploiting a compromised user account to take control of the system.

Sudo Command: Administrative tasks are typically carried out using sudo (superuser do), which provides controlled, time-limited access to root privileges. This limits potential damage by preventing unnecessary exposure of administrative rights.

3. Strong File Permissions and Ownership

Linux enforces strict file permissions for users and groups, ensuring that only authorized users can access, modify, or execute files. This is a fundamental aspect of Linux's security model, making it difficult for unauthorized users or malware to alter important system files.

Each file has an owner, a group, and a set of permissions (read, write, execute), allowing for detailed control over who can do what with each file.

4. Security Modules and Features

SELinux (Security-Enhanced Linux): This is a set of kernel-level security enhancements that implement mandatory access control (MAC). It adds an additional layer of security by enforcing strict access policies that restrict how processes interact with the system and each other.

AppArmor: Similar to SELinux, AppArmor is a security module that restricts programs to a set of predefined security profiles, preventing them from performing unauthorized actions.

Chroot and Namespaces: These tools allow isolation of processes, limiting the damage they can do even if compromised.

5. Frequent Security Patches

The Linux community is very active in identifying and fixing vulnerabilities. Most Linux distributions offer regular updates, including security patches, making it quick and easy to keep the system secure.

Security advisories and patches for distributions (like Debian, Ubuntu, or Red Hat) are generally well-documented and quickly available.

6. Minimal Attack Surface

Linux distributions can be customized to include only the necessary components, reducing the attack surface. Users can install a minimal version of Linux with only the essential software, which reduces the number of potential vulnerabilities.

Many server-focused Linux distributions, such as CentOS or Ubuntu Server, come with fewer default applications, reducing the chances of exploitable vulnerabilities.

7. Robust Package Management

Package managers like apt, yum, and dnf ensure that software installed on Linux is vetted and comes from trusted repositories. This reduces the risk of installing malicious or untrusted software.

Additionally, Linux distributions often come with tools to verify the integrity of installed packages and update software automatically.

8. Lower Target for Malware

Popularity in Specific Use Cases: While Linux is widely used for servers, many personal users still prefer other operating systems (like Windows). This makes Linux less of a target for mass-market malware.

Open-Source Security Tools: Many Linux distributions have strong built-in security tools, and the OS itself is often the platform for security professionals and penetration testers, further boosting its reputation as a secure platform.

9. Security by Design

Linux has security mechanisms built into its design, such as:

Stack Protection: Linux uses techniques like stack canaries and non-executable memory to prevent stack-based buffer overflow attacks.

Data Execution Prevention (DEP): This feature prevents code from executing in areas of memory that should contain only data.

Address Space Layout Randomization (ASLR): Randomizing memory addresses for processes makes it harder for attackers to predict the location of critical system functions.

10. Regular Security Audits and Penetration Testing

Since many security professionals and ethical hackers use Linux, the system is often subjected to rigorous security testing. This helps find vulnerabilities before they are exploited in real-world attacks.

Conclusion

Linux's security is driven by its open-source nature, strong access controls, and a thriving community that quickly identifies and fixes vulnerabilities. Combined with its robust security tools, regular updates, and user-centric design, it offers a highly secure environment, making it a popular choice for critical applications like web servers, networking, and cloud computing. However, like any system, its security ultimately depends on how it's configured and maintained.

AlloyDB Omni Version 15.7.0 Improves PostgreSQL Workflows

AlloyDB Omni boosts performance with vector search, analytics, and faster transactions.

With its latest release AlloyDB Omni version 15.7.0, AlloyDB Omni is back and is significantly improving your PostgreSQL workflows. These improvements include:

Quicker performance

A brand-new, lightning-fast disk cache

A better columnar engine

The widespread use of ScANN vector indexing

The AlloyDB Omni Kubernetes operator has been updated.

In your data center, on the edge, on your laptop, in any cloud, and with 100% PostgreSQL compatibility, this update offers on all fronts, from transactional and analytical workloads to state-of-the-art vector search.

AlloyDB Omni version 15.7.0 is now broadly accessible (GA). The following updates and features are included in version AlloyDB Omni version 15.7.0:

AlloyDB Version 15.7 of PostgreSQL is supported by Omni.

Previously known as postgres_scann, the alloydb_scann extension is now generally available (GA).

There is generally available (GA) support for Red Hat Enterprise Linux (RHEL) 8.

You can preview the AlloyDB Omni columnar engine on ARM.

Because disk cache and columnar storage cache speed up data access for AlloyDB Omni in a container and on a Kubernetes cluster, they can enhance AlloyDB Omni performance.

It has applied security updates for CVE-2023-50387 and CVE-2024-7348.

The documentation for the AlloyDB Omni Reference is accessible. This comprises AlloyDB Omni 15.7.0 metrics, database flags, model endpoint management reference, and extension documentation.

AlloyDB The pg_ivm extension, which offers incremental view maintenance for materialized views, is compatible with Omni.

Numerous efficiency enhancements and bug fixes.

Let’s get started.

Improved performance

When compared to regular PostgreSQL, many workloads already experience an improvement. For transactional workloads, AlloyDB Omni outperforms regular PostgreSQL by more than two times in performance testing. The majority of the tuning is done automatically for you without the need for additional setups. The memory agent that maximizes shared buffers while preventing out-of-memory issues is one of the main benefits. AlloyDB Omni generally runs better with more memory configured because it can serve more queries from the shared buffers and eliminate the need for disk calls, which can be significantly slower than memory, especially when utilizing durable network storage.

An extremely fast disk cache

The introduction of an ultra-fast disk cache also made the trade-off between memory and disk storage more flexible. As an extension of Postgres’ buffer cache, it enables you to set up a quick, local, and perhaps brittle storage device. AlloyDB Omni can store a copy of not-quite-hot data in the disk cache, where it can be accessed more quickly than from the permanent disk, rather than aging out of memory to create room for new data.

Improved columnar engine

The analytics accelerator from AlloyDB Omni is revolutionizing mixed workloads. Because it eliminates the need to manage additional data pipelines or databases, developers are finding it helpful for extracting real-time analytical insights from their transactional data. To speed up queries, you can instead activate the columnar engine, allocate a piece of your memory to it, and let AlloyDB Omni to choose which tables or columns to load in the columnar engine. The columnar engine outperforms regular PostgreSQL by up to 100x in our benchmarks for analytical queries.

The amount of RAM you can allocate to the columnar engine dictates the analytics accelerator’s practical size limit. The ability to set up a quick local storage device for the columnar engine to spill to is a new feature. This expands the amount of data on which you may do analytical queries.

SCaNN becomes GA

Finally, AlloyDB Omni already provides excellent performance with pgvector utilizing either the ivf or hnsw indexes for vector database use cases. Vector indexes, however, can be slow to build and reload even though they are a terrific method to speed up queries. It added the ScaNN index as an additional index type at Google Cloud Next 2024. The ScaNN index from AlloyDB AI provides up to 4 times faster vector queries than the HNSW index used in ordinary PostgreSQL. ScaNN offers substantial benefits for practical applications beyond only speed:

Rapid indexing: With noticeably quicker index build times, you may expedite development and remove bottlenecks in large-scale deployments.

Optimized memory usage: Cut memory usage by three to four times as compared to PostgreSQL’s HNSW index. This improves performance for a variety of hybrid applications and enables larger workloads to operate on smaller hardware.

In general, AlloyDB AI ScANN indexing is accessible as of AlloyDB Omni version 15.7.0.

A fresh Kubernetes administrator

Google Cloud has published version 1.2.0 of the AlloyDB Omni Kubernetes operator in addition to the latest version of AlloyDB Omni. With this release, you can now configure high availability to be enabled when a disaster recovery secondary cluster is promoted to primary, add more configuration options for health checks when high availability is enabled, and use log rotation to help manage the storage space used by PostgreSQL log files.

Version 1.2.0 of the AlloyDB Omni Kubernetes operator is now broadly accessible (GA). The following new features are included in version 1.2.0:

The interval between health checks can be set in seconds using the healthcheckPeriodSeconds option.

You can keep an eye on your database container’s performance with the following metrics. These measurements are all type gauge.

A database container’s memory limit is displayed by alloydb_omni_memory_limit_byte.

All replicas connected to the AlloyDB Omni primary node are shown in alloydb_omni_instance_postgresql_replication_state.

The database container’s memory usage is displayed in bytes via alloydb_omni_memory_used_byte.

When the following is true, a problem that briefly disrupted all database clusters has been resolved:

The AlloyDB Omni Kubernetes operator version 1.1.1 is being upgraded to a more recent version.

Version 15.5.5 or higher of the AlloyDB Omni database is what you’re using.

AI for AlloyDB is not activated.

Once promoted, high availability is supported on a secondary database cluster.

Model endpoint management can be enabled or disabled using Kubernetes manifests.

By setting thresholds depending on the size of the log files, the amount of time since the log file last rotated, or both, you may control when logs rotate.

To examine and troubleshoot the memory performance of the AlloyDB Omni Kubernetes operator, you can take a snapshot of its memory heap.

Note: Parameterized view features were accessible via the alloydb_ai_nl extension of AlloyDB Omni versions 15.5.5 and earlier. The parameterized_views extension, which you must develop before using parameterized views, contains the parameterized view features starting in AlloyDB Omni version 15.7.0. The associated function, google_exec_param_query, has also been renamed to execute_parameterized_query and is accessible through the parameterized_views extension as of AlloyDB Omni version 15.7.0.
