Snowflake in 2020
If you are working in the Information Technology space and you have not heard of Snowflake this year, there’s a good chance you have been locked in the cupboard. After recently closing their first day trading at 100% over their IPO price, they are clearly a stock to watch in the future.
Fistfuls of dollars aside, Snowflake is getting the attention of companies around the world that - to date - may not have embarked convincingly on their cloud journey. For this audience in particular, it offers a TCO that is simple to understand, and a technical platform that is both novel and fundamentally sustainable. That’s a lifeline to many a CTO out there whose data and analytics capabilities are struggling to stay in the race, and them with it.
Snowflake are obviously not alone in this field; competitors such as Google Cloud Platform’s BigQuery, AWS Redshift, but also Hadoop players such as Cloudera crowd the field, baited by yet newer cloud native competitors such as FireBolt and RockSet. However, few match the broad appeal and favour currently experienced by Snowflake that appears to strike a compelling equilibrium between engineering talent and data services cost.
Today we talk about upcoming Snowflake Organization support, what it is, and what it might mean for the way you use Snowflake.
Emergence of Snowflake Organization Support
Most people likely experience Snowflake through a single or paired accounts (prod and dev). For many companies and organisations, this will do just fine (some don’t even create separate dev accounts). Until recently, creating additional Snowflake accounts has been a task managed by Snowflake Support teams; typically to create in another cloud, or separate region.
Recently, Snowflake has been privately previewing an Organizations capability; with references to the feature now appearing on pages about cross cloud sharing and replication, one would have to expect this feature will land in public preview very shortly.
Scholarly comments about multi-cloud are numerous, and whilst I definitely don’t want to enter that debate today, Snowflake’s hegemonious approach to cloud data warehousing allows them not only to comfortably operate on the top tier public clouds, but also facilitates interoperation between them, by allowing you to replicate across different cloud platforms and regions.
What does Snowflake Organization Support offer you?
Essentially, Snowflake Organizations allows you to be in control of your Snowflake account vending. It means you as a customer can create new accounts
- in different geographical locations
- on different public cloud platforms
In addition, only accounts belonging to a Snowflake Organization can replicate databases from one account to another. If you are doing this already without access to Snowflake Organizations, it’s likely because Snowflake is managing the account membership of your organization for you.
I won’t cover the specifics of the account vending, because as a private preview feature it is still possible the details will change (refer to the referenced documentation for details), though you should note at this time that account removal appears to require a support request.
Multi Organizational Capability
Maintaining multiple Snowflake Organizations can be used to enable:
- Separate / Split Billing across an organisation
- Independent ownership / accountability with shared management
Yet it also comes with complications that we will elaborate on later.
Single Organization Features
Remaining in a single Snowflake Organization carries a number of key benefits
- Use of the Snowflake Private Data Exchange across your Snowflake Organization accounts as a way to catalog, publish and discover datasets within your participating accounts.
- Replication of databases across cloud regions
- Consolidated Billing with per account breakdown

Hypothetical Use Cases
Multi National Corporations with Subsidiaries
Many large multi-nationals are dispersed not only geographically, but in function or capability. Others operate globally, but with regional locality (or subsidiaries).
In a recent AWS Big Data Blog, Toyota describe how they rolled out a serverless data lake and analytics capability, to service their burgeoning in-car telemetry data.
Reasons such as sovereignty, cost or latency may dictate that the journeys your data make within your organisation vary, depending on the region in which they originate. Independent Snowflake Organizations can be a good way to support autonomous subsidiaries or joint ventures that have a likelihood of future secession.
Loosely Coupled Organisations with broad purpose
A different scenario is where you have a number of organisations that are similar in function, united by purpose, yet operated and governed independently of each other (and possibly even subject to separate jurisdictions or legislation.
In Australia, an example of this could be the 31 Primary Health Networks (PHNs) that locally co-ordinate the appropriate network of health providers for all Australians. Each PHN is responsible for acquisition of patient data from relevants providers, and as such collectively manage a vast potential data portfolio that is of powerful consequence to government agencies that focus on national health outcomes and policy, such as the Australian Institute of Health and Welfare.
As Australia is a federation of States and Territories, it follows that each jurisdiction can and generally does have some of its own laws relating to privacy, especially in relation to public agencies. In these scenarios, it may be prudent for each jurisdiction to have their own Snowflake Organization that can be administered independently of those in other states, whilst retaining the capability to share data within the same region.
It’s important to note that one of Snowflake’s key features - simple cross account sharing of data - is independent of the Snowflake Organization feature. Accounts do not have to belong to the same Snowflake Organization to share data.
However, sharing can only happen within the same cloud region. This is important to understand, as it effectively means you must replicate your data (and hence pay storage again) in order to share across the cloud / region boundaries.
I’ve omitted the simplest use case of a single Snowflake organization with a single account, as this is the default for most people when they onboard with Snowflake.
Multiple Snowflake Organizations
In this pattern we imagine a global car manufacturing corporation, Foryota, that has subsidiaries around the world. Each essentially runs autonomously yet the corporate parent still wants to be able to share data for global efficiencies of scale.
In the following diagram, you will note that in order to share with accounts in a destination region (e.g. Tokyo), a remote organization must first replicate its data to an account in its own Snowflake Organization - in the same destination region - before it can be shared with an account from another Snowflake Organization.
While there may be genuine reasons for requiring individual Snowflake Organizations, it will add complexity and likely some additional cost as well.
Single Organization, Multiple Regions / Clouds, Multiple Accounts
Next is an alternative structure that keeps everything managed through a single Snowflake Organization. This allows accounts to replicate some of their databases to other accounts in the organization that operate in different cloud regions, effectively opening up opportunities for cross cloud / region sharing.
This scenario is likely to be a common choice for many geographically or multi cloud businesses. It can also be an effective cross cloud / region redundancy architecture, where databases can be failed over to alternate regions to which they are being replicated.
Single Organization, Single Region / Cloud, Multiple Accounts
This is going to be perhaps the most common pattern for many large organisations that work within a single cloud region. By working in a single cloud region, cross account sharing is supported. Master and reference data sets can be shared by a corporate account for access by all other divisional accounts within the same region.
Think about the money
How should you make sense of all this when it comes to cost? The following page lists the associated costs of Snowflake usage across clouds and regions, and it has some important dimensions to consider, notably:
- On-demand credit cost varies significantly by region
- Expect to pay between $100-$200 per TB transferred out of regions, except within AWS regions in North America where it can be as low as $20 per TB
- Storage costs are fairly consistent globally, both across regions and clouds
This was a brief introduction to Snowflake Organizations, and how it relates to support for secure sharing between accounts and recently released features such as database replication across cloud regions.
With Snowflake, cost modelling and management is critical to maximising your value from the service. Customers should weigh carefully the different options and implications, to match their aspirations and capabilities appropriately.
