Data Centers - Striving Within A Narrow Range - Research Report - MCG - May 2...pchutichetpong
M Capital Group (“MCG”) expects to see demand and the changing evolution of supply, facilitated through institutional investment rotation out of offices and into work from home (“WFH”), while the ever-expanding need for data storage as global internet usage expands, with experts predicting 5.3 billion users by 2023. These market factors will be underpinned by technological changes, such as progressing cloud services and edge sites, allowing the industry to see strong expected annual growth of 13% over the next 4 years.
Whilst competitive headwinds remain, represented through the recent second bankruptcy filing of Sungard, which blames “COVID-19 and other macroeconomic trends including delayed customer spending decisions, insourcing and reductions in IT spending, energy inflation and reduction in demand for certain services”, the industry has seen key adjustments, where MCG believes that engineering cost management and technological innovation will be paramount to success.
MCG reports that the more favorable market conditions expected over the next few years, helped by the winding down of pandemic restrictions and a hybrid working environment will be driving market momentum forward. The continuous injection of capital by alternative investment firms, as well as the growing infrastructural investment from cloud service providers and social media companies, whose revenues are expected to grow over 3.6x larger by value in 2026, will likely help propel center provision and innovation. These factors paint a promising picture for the industry players that offset rising input costs and adapt to new technologies.
According to M Capital Group: “Specifically, the long-term cost-saving opportunities available from the rise of remote managing will likely aid value growth for the industry. Through margin optimization and further availability of capital for reinvestment, strong players will maintain their competitive foothold, while weaker players exit the market to balance supply and demand.”

Empowering the Data Analytics Ecosystem: A Laser Focus on Value
The data analytics ecosystem thrives when every component functions at its peak, unlocking the true potential of data. Here's a laser focus on key areas for an empowered ecosystem:
1. Democratize Access, Not Data:
Granular Access Controls: Provide users with self-service tools tailored to their specific needs, preventing data overload and misuse.
Data Catalogs: Implement robust data catalogs for easy discovery and understanding of available data sources.
2. Foster Collaboration with Clear Roles:
Data Mesh Architecture: Break down data silos by creating a distributed data ownership model with clear ownership and responsibilities.
Collaborative Workspaces: Utilize interactive platforms where data scientists, analysts, and domain experts can work seamlessly together.
3. Leverage Advanced Analytics Strategically:
AI-powered Automation: Automate repetitive tasks like data cleaning and feature engineering, freeing up data talent for higher-level analysis.
Right-Tool Selection: Strategically choose the most effective advanced analytics techniques (e.g., AI, ML) based on specific business problems.
4. Prioritize Data Quality with Automation:
Automated Data Validation: Implement automated data quality checks to identify and rectify errors at the source, minimizing downstream issues.
Data Lineage Tracking: Track the flow of data throughout the ecosystem, ensuring transparency and facilitating root cause analysis for errors.
5. Cultivate a Data-Driven Mindset:
Metrics-Driven Performance Management: Align KPIs and performance metrics with data-driven insights to ensure actionable decision making.
Data Storytelling Workshops: Equip stakeholders with the skills to translate complex data findings into compelling narratives that drive action.
Benefits of a Precise Ecosystem:
Sharpened Focus: Precise access and clear roles ensure everyone works with the most relevant data, maximizing efficiency.
Actionable Insights: Strategic analytics and automated quality checks lead to more reliable and actionable data insights.
Continuous Improvement: Data-driven performance management fosters a culture of learning and continuous improvement.
Sustainable Growth: Empowered by data, organizations can make informed decisions to drive sustainable growth and innovation.
By focusing on these precise actions, organizations can create an empowered data analytics ecosystem that delivers real value by driving data-driven decisions and maximizing the return on their data investment.
Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.

(30 seconds): Let’s take a look at data load performance. With the pgbench benchmark, you first have to load the database. We compared the time it takes to load, vacuum, and build indexes for a scale 10000, or 150GB, pgbench database. As you can see, Amazon Aurora can finish the pgbench initialization phase about 3 times faster than PostgreSQL. Most of the performance difference in load times is due to the database-specific storage optimizations that are key to Amazon Aurora storage – we will dive deeper into those optimizations in a few minutes.
(1 minute): In all the tests we have shown you, we have tried to tune PostgreSQL to deliver the best possible performance results. One key part of that tuning is to reduce the number of checkpoints by increasing the duration between checkpoints. One consequence of that is it increases recovery time if there is a database failure. This is because when recovering from a crash, PostgreSQL has to start from the last checkpoint – the last time it wrote all dirty pages from memory to storage – and roll forward through all the Write-Ahead Log – or WAL – records written since the last checkpoint. The more WAL to roll forward, the longer recovery will take. With Amazon Aurora, there are no checkpoints needed, so recovery time is independent of checkpoints, and independent of how many transactions are being processed by the database. As you can see in the graph, as we increased the checkpoint time for PostgreSQL, the overall throughput increased, but so did the recovery time. At the best throughput level for PostgreSQL, the recovery time for Aurora was 85X faster than for PostgreSQL, and Aurora delivered more than 92 thousand writes per second compared with just under 70 thousand writes per second from PostgreSQL.
(1 minute) Let’s first look at some pgbench results. Pgbench is the standard benchmark that is part of the PostgreSQL distribution, and it has several built-in modes. One of those modes is tpcb-like, in which pgbench runs transactions that are very similar to the standard TPC-B transaction. We ran pgbench in tpcb-like mode while increasing the number of concurrent client connections from 256 up to 1,536. We used a 30GB scale 2000 size database, and we ran each test for 60 minutes. As you can see in the graph, PostgreSQL reaches a peak of just under 18 thousand transactions per second at 512 connections, whereas Amazon Aurora continues to scale up as more connections are added, reaching a peak of just over 38 thousand transactions per second at 1,024 connections. The peak-to-peak comparison shows Amazon Aurora delivers more than 2x the throughput of PostgreSQL, and the direct comparison of Amazon Aurora’s peak with the corresponding PostgreSQL result with 1,024 connections shows a ratio of greater than 2 ½ times.
(30 seconds) In this test, we used sysbench, a benchmark utility often used to compare different database engines. We ran the sysbench write-only benchmark, again while increasing the number of client connections, with a 30GB database. PostgreSQL scales up until reaching more than 47 thousand writes per second at 1,024 connections, then the throughput drops as more connections are added; Amazon Aurora scales up to more than 92 thousand writes per second at 1,536 connections, about 2x more throughput when comparing peak to peak. Compared directly with the PostgreSQL throughput with 1,536 connections, the ratio is more than 2 ½ X.
(1 minute) It’s important to measure throughput, but it’s also important to measure response time at scale. So, we looked at sysbench response times, with 1,024 concurrent connections. On the graph you can see very different behavior for Amazon Aurora as compared with PostgreSQL: the response times for Aurora are much steadier, with much less variation. More precisely, based on measuring the standard deviations of the two data sets, Amazon Aurora is more than 10x more consistent than PostgreSQL. Also, the average response time is about 2.9x lower. So, Aurora delivers much faster response times with much less variability. You might wonder what’s going on with the PostgreSQL results. What you see is the impact of database checkpoints, which PostgreSQL does to ensure that dirty pages in memory are periodically written to storage to ensure recovery time from a crash isn’t extended too long. During a checkpoint, PostgreSQL will do a lot of writes, which will slow down user transactions, hence the variability in the PostgreSQL response times.
------------ NOTES ONLY – DO NOT USE ---------------
On the sysbench response time graph: Stddev(POPS) is 96.97ms. Stddev(Manny) is 7.38ms. 13x more consistent (although I prefer “greater than 10x”)
Avg(POPS) is 201ms, avg(Manny) is 69ms. So this is really 2.9x lower response times
(3x would be 207, but who’s counting…)
On the sysbench response time graph: Stddev(POPS) is 96.97ms. Stddev(Manny) is 7.38ms. 13x more consistent (although I prefer “greater than 10x”)

(30 seconds): Let’s go back to pgbench to look at consistent perfornance based on throughput. In this graph, higher is better, as we’re showing the throughput while running pgbench in tpcb-like mode. We ran each database at the optimal number of clients to deliver max throughput for that database, and plotted the variability in throughput over time. As you can see, Amazon Aurora is much more consistent, and delivers significantly higher throughput: based on standard deviation, Aurora is about 3x more consistent than PostgreSQL.
[On the pgbench throughput graph: stddev(POPS) is 5080 tps. Stddev(Manny) is 1395 tps. 3.6x more consistent (again, I hate over precision, so “3x” is my preference).]
(1 minute): In this test, we compared how each database scales in terms of throughput as the database size scales, using the sysbench write-only workload. As you can see, with a 10GB database, Aurora delivers about 1.5X better throughput; with a 100GB database Aurora delivers about 3X better throughput. Aurora can handle larger databases and workloads significantly better than PostgreSQL.
