Generally, Data Lake will be a bit more expensive although they are in close range of each other. Blob storage has more options for pricing depending upon things like how frequently you need to access your data (cold vs hot storage). Data Lake is priced on volume, so it will go up as you reach certain tiers of volume.

The anti-money laundering specialist should recommend a financial institution to investigate the source of funds, identify people and companies that are clearly related, and identify a person fully, including their political history, when dealing with individuals holding important public positions. These are essential steps to conduct enhanced due diligence based on public information, as they can help to assess the risk profile, the legitimacy, and the transparency of the customer relationship. The Basel Committee on Banking Supervision's list of public officials is not a reliable source of public information, as it is not comprehensive, updated, or verified. Therefore, it is not a sufficient criterion to check the background of potential customers.

Explanation
Undermining the Legitimate Private Sector: One of the most serious microeconomic effects of money laundering is felt in the private sector. Money launderers are known to use front companies: businesses that appear legitimate and engage in legitimate business but are in fact controlled by criminals who commingle the proceeds of illicit activity with legitimate funds to hide the ill-gotten gains. These front companies have a competitive advantage over legitimate firms as they have access to substantial illicit funds, allowing them to subsidize products and services sold at below market rates. This makes it difficult for legitimate businesses to compete against front companies. Clearly, the management principles of these criminal enterprises are not consistent with traditional free market principles, which results in further negative macroeconomic effects

A financial institution should examine the country or location where the customer is from or does business, the type and size of the business the customer runs, and the legal structure of the customer's business, because these factors can indicate the level of money laundering risk associated with the customer. For example, some countries or locations may have weak anti-money laundering laws or high levels of corruption, some types or sizes of businesses may be more prone to generating or concealing illicit funds, and some legal structures may be more complex or opaque than others, making it harder to identify the beneficial owners or controllers of the customer.
