AlloyDB Outperforms Self-Managed PostgreSQL in Cloud

 

PostgreSQL Database AlloyDB

The open-source, extensively developed PostgreSQL database is a relational database management system with strong, stable, and scalable database solutions. It has several properties, like as performance, availability, and security, that ensure data integrity and business continuity. Businesses searching for a versatile database foundation for their essential applications can choose PostgreSQL database as it offers an economical and adaptable substitute for proprietary database systems. Its widespread extensibility and vibrant community support provide even more allure.


In the meantime, Google Cloud's fully managed, enterprise-grade PostgreSQL database service, AlloyDB, maintains full compatibility with the standard PostgreSQL database engine while incorporating several improvements: AlloyDB outperforms standard PostgreSQL databases in terms of performance, availability, and scalability to manage even the most taxing workloads. In addition, AlloyDB offers intelligent resource optimisation, automated database maintenance, and quicker analytical queries by utilising machine learning and Google's distinct architecture. This makes AlloyDB an appealing choice for companies looking for a reliable and effective PostgreSQL-compatible solution. So which one should you choose?


AlloyDB, which offers up to 4x better transactional performance on the same-sized instance and up to 2x better price-performance than self-managed PostgreSQL, was shown by Google Cloud at Google Cloud Next 24. This post explores the data that underlies that comparison in more detail and emphasises  AlloyDB's additional advantages.

Differentiating performance

Google Cloud brought transactional and query processing layers to PostgreSQL's kernel along with self-managing autopilot features including adaptive vacuum management and automatic memory management using AlloyDB. When paired with its intelligent distributed storage solution and automatic storage tiering, AlloyDB performs better than standard PostgreSQL.

Google Cloud performed a performance comparison test, accounting for both cost per transaction and total cost of ownership (TCO), to assess how cost-effective AlloyDB is in comparison to self-managed PostgreSQL running on Google Compute Engine (GCE). Google Cloud compared AlloyDB for PostgreSQL databases configured with HA on 8 vCPU / 64 GB Memory to self-managed PostgreSQL 15 running on two VMs ready for HA, each with 16 vCPU / 128 GB Memory:



AlloyDB showed superior TPM even with only 50% of its processing resources configured for self-management. Price-performance and performance can be up to two times greater than with self-managed average PostgreSQL database workloads when databases are configured to cache thirty percent of the data. AlloyDB's CPU usage of nearly 90% suggests that the kernel is utilising available resources far more effectively.


The identical GCE SKU (16 vCPU/128GB) was used for AlloyDB deployment, which resulted in a 4x speed boost. AlloyDB's scalability architecture allows for bigger vCPU counts while maintaining better price-performance. AlloyDB can presently support up to 128 virtual CPUs, or 864GB of RAM.


Resources like as CPU scaling issues and IOPS limitations make it difficult to handle large amounts of data on Compute Engine using a regular PostgreSQL database. Note that neither the manual resources required for the database to self-manage nor any additional inter-zone networking fees that could increase overall costs are covered by this analysis.

Additional financial savings

In a cluster, compute instances of AlloyDB use the same local colossus storage. This indicates that all replica nodes added during the deployment of HA up to 20 at the time this blog was published share the same storage. For example, in a self-managed system, your storage expenses (one primary, one standby, and four read nodes) will be six times the capacity if you have a 5TB database with HA and four read replicas. When utilising AlloyDB, you will just have to pay for a single 5TB charge.

Moreover, setting up extra space for IOPS and pre-provisioning AlloyDB's storage capacity are not required. AlloyDB's cloud-scale architecture makes it possible for storage use to be dynamic, expanding and contracting in response to demand. You are only charged for the capacity that you really use.


AlloyDB offers free cross-zone data replication for high availability and replicating databases. With read replica lag as low as 25x, you may expand horizontally using the same storage and data that is nearly real-time.


AlloyDB can also be used as a single datastore for workloads involving vector, analytical, and transactional databases. These applications do not require many databases, so additional processing, storage, networking, and ETL implementation and maintenance are not needed.

Although running PostgreSQL databases on your own infrastructure can result in cost savings, there are a number of disadvantages and extra costs. These include scheduling capacity for peak workloads, managing hardware resources on a continual basis, and manually managing critical database processes including scaling, deployment, security, high availability, backups, and disaster recovery. As a result, your team can get overworked, and administrative costs might go up.

AlloyDB provides a fully managed experience that meets these standards as well as a 99.99% uptime SLA, including maintenance, to enable you run your mission-critical applications.

AlloyDB becomes victorious

Compared to self-managed PostgreSQL databases, AlloyDB offers up to a twofold price-performance increase and shared regional storage. Additionally, by automating tedious administrative tasks, offering little maintenance downtime, offering on-demand vertical (read/write) and horizontal (read-only) scalability, and integrating columnar engine & AI capabilities, AlloyDB significantly lessens the challenges associated with self-managed databases. With these features and benefits, AlloyDB provides self-managed PostgreSQL configurations with a better, faster, and more cost-effective choice.
