What Is Cloud Egress? And Why it SUCKS!

Your Cloud Storage Might Have a Hidden Cost You Didn’t Know About – Egress!

The often-overlooked costs associated with cloud data egress, the process of downloading data from the cloud, can be substantial. While services like Google, Amazon, and others offer affordable storage rates, the hidden costs of retrieving data should be thoroughly understood by businesses and individuals alike. These costs can catch users off-guard, transforming an initially economical solution into an unexpectedly expensive one.

Understanding Egress and Its Impact

Egress, essentially the act of downloading data from the cloud, is often not fully disclosed by cloud providers who typically advertise low storage costs but obscure the expensive egress fees. This lack of transparency can lead to significant financial strain, especially for users who need to access large amounts of data frequently. Cloud providers usually emphasize the affordability and scalability of their storage solutions, drawing customers in with promises of low monthly fees and high availability. However, the details regarding data retrieval costs are often buried in fine print or hidden in complex pricing structures.

The impact of egress costs becomes evident when businesses or individuals start to retrieve their stored data. Frequent data access can quickly escalate expenses, leading to budget overruns and financial difficulties. For example, businesses that rely on cloud storage for their operational data, backups, or disaster recovery plans may find themselves paying exorbitant fees just to access their own information. This can hinder their ability to manage cash flow effectively and invest in other critical areas of their operations. Moreover, the unpredictable nature of egress costs adds another layer of complexity. Unlike fixed storage fees, which are easy to budget for, egress fees can vary widely depending on the volume of data retrieved and the frequency of access. This variability makes it challenging to forecast expenses accurately, potentially resulting in unpleasant surprises when the bills arrive. For users with high data retrieval needs, understanding the full scope of egress costs is crucial for making informed decisions about their cloud storage solutions.

Egress Cost Example

Storing 20 terabytes of data in the cloud might seem economical initially. However, downloading just one terabyte per month can drastically increase costs, making cloud storage more expensive than anticipated. These egress fees can add up quickly, transforming a seemingly cost-effective storage solution into a financial burden. For instance, if a business needs to access a significant portion of its stored data regularly, the cumulative egress fees over a year can far exceed the initial savings on storage costs.

Consider a scenario where a company uses cloud storage for its customer data, project files, and backups. With 20 terabytes stored, the monthly storage fee might be manageable and within budget. However, if the company needs to retrieve 1 terabyte of data every month, the egress fees could be substantial. Assuming an average egress fee of $0.09 per gigabyte, downloading 1 terabyte (1,024 gigabytes) would cost approximately $92.16 per month. Over a year, this amounts to over $1,100, a significant addition to the company’s expenses. This example highlights the importance of not only considering storage costs but also factoring in potential egress fees when evaluating cloud storage solutions. Businesses must assess their data retrieval patterns and calculate the total cost of ownership, including both storage and egress fees, to make informed decisions. Ignoring these costs can lead to financial strain and disrupt operational budgets, especially for small and medium-sized enterprises with limited financial resources.

Business Implications

Businesses with substantial data needs or frequent data retrievals face significant egress charges. Scenarios such as backing up multiple sites, restoring data after disasters, or permanently moving data off the cloud can incur hefty costs. These unexpected expenses can strain budgets and impact financial planning, making it essential for businesses to thoroughly understand and anticipate these charges when choosing a cloud storage solution.

Highlighting Egress Issues Through Scenarios

1. Multiple Office Locations: Backing up to a central cloud can incur hidden egress costs due to background data transfers and synchronization. Even routine operations can result in significant costs.
2. Single Office with Multiple PCs: If a disaster occurs and all data needs to be restored, high egress costs can be incurred. This highlights the risk of depending solely on cloud storage without accounting for potential recovery costs.
3. Moving Away from Cloud Storage: High costs associated with downloading all stored data within a limited time frame can be a major issue, making the transition to different storage solutions prohibitively expensive.

Comparing Cloud Egress Costs with Private NAS Ownership

When examining cloud storage costs versus owning a private NAS, it’s essential to consider both initial and ongoing expenses. Cloud storage services like Dropbox, Google Drive, and OneDrive often have low entry costs but can accrue significant fees over time due to egress charges. For example, Dropbox offers 2TB for £7.99/month (or £95.88/year), and Google Drive provides 2TB for £79.99/year. While these rates may seem affordable, the costs can quickly escalate when factoring in egress fees for data retrieval. This can lead to unpredictable expenses that disrupt budget planning.

In contrast, investing in a NAS offers a more predictable and VERY flexible cost structure. For instance, a high end enterprise solution like the QNAP TS-H2477XU-RP NAS server is priced at approximately £5,769.59, whereas the desktop sized Synology 4TB BeeStation Personal Cloud NAS Server costs around $219.99 and included the storage. While the upfront costs for NAS equipment can be highly dependant of the scale of your business/requirements, they provide unlimited access to your data without additional retrieval fees. This makes NAS a more cost-effective solution for businesses and individuals who require frequent and extensive data access, offering better long-term value and financial predictability.

Additionally, NAS solutions offer greater control over data management and security. Unlike cloud services that depend on third-party policies and infrastructure, NAS devices allow users to manage their data locally, ensuring it remains accessible without incurring additional costs. In recent years, the jumping off point for prosumers and smaller scale users has been 4-Bay solutions like the $550 DS923+ or the QNAP TS-464 4-Bay NAS Enclosure at $565.00. Whereas BASIC storage is still popular and affordable as just simple google drive/dropbox alternatives (such as the DS223 from Synology or the QNAP TS-233-2-Bay NAS Enclosure at $199.00 provide scalable storage solutions with no recurring egress fees. This level of control and predictability is particularly valuable for businesses with large data volumes or sensitive information, making NAS an attractive alternative to cloud storage.

Performance Comparison: Cloud vs. NAS

Another significant factor to consider is performance. Cloud storage performance is often limited by the upload and download speeds at each site. This can be a bottleneck, especially in regions with slower internet connections. In contrast, NAS systems start at gigabit network speeds and can be quickly upgraded to 10GbE, 25GbE, and even 100GbE as needed. This flexibility allows NAS users to achieve much higher data transfer rates, enhancing productivity and reducing downtime.

For example, the Synology DS1522+ NAS Drive with a 10GbE E10G22-T1-mini Add-on demonstrates impressive performance, capable of handling high-speed data transfers efficiently. Similarly, hard drives like the WD Red Pro 22TB and Seagate IronWolf Pro 20TB and 24TB offer robust performance metrics, as seen in their benchmark results, making them ideal for demanding NAS environments. The ability to upgrade NAS systems with high-speed network interfaces ensures that users can meet their evolving performance needs without being constrained by the limitations of their internet connection.

Provider/Device	Storage Cost	1 TB Download Cost	Performance
Dropbox	£7.99/month (2TB)	£0.09/GB	Limited by internet speed
Google Drive	£79.99/year (2TB)	£0.09/GB	Limited by internet speed
QNAP TS-464 NAS	$565.00	None	Starts at 2.5gigabit, upgradeable to 10GbE
Synology DS1522+	$199.00	None	High performance with 10GbE upgrade

ROI and TCO Considerations

Return on Investment (ROI) and Total Cost of Ownership (TCO) are critical in deciding between cloud storage and NAS:

• Cloud Storage: Low initial cost but high long-term costs due to recurring fees and egress charges. Suitable for short-term or low-volume data storage, but less cost-effective over time.
• NAS: Higher initial investment but lower long-term costs. Suitable for businesses with large or frequently accessed data, offering better ROI over time. The higher initial investment in NAS can pay off in the long run with lower operational costs and greater control over data.

Metric	Cloud Storage	NAS
Initial Investment	Low	High
Long-term Costs	High	Low
ROI	Lower over time (due to recurring costs)	Higher over time (due to cost savings)
TCO	Higher (includes monthly and egress fees)	Lower (mainly initial and maintenance)

Business and Personal Considerations

For businesses, the decision between cloud storage and NAS can significantly impact their operational costs. Companies with large data volumes or frequent retrieval needs will benefit from the predictable costs of NAS. Personal users, on the other hand, might find cloud storage more convenient but should still be aware of potential egress charges. It is essential for both business and personal users to consider their specific needs and usage patterns when choosing between these options, ensuring that their choice aligns with their long-term data management strategy.

Planning for the Future

For businesses and individuals considering cloud storage, it’s crucial to plan for potential egress costs. This includes understanding the provider’s egress policies and possibly integrating cloud storage as part of a multi-tier backup strategy that leverages both cloud and local storage to optimize costs and access speed.
