Looker vs. Power BI: the showdown

In this comparison, we will evaluate Looker and Power BI across key business and technological aspects, ranging from pricing models to data security and data visualization. Additionally, we will incorporate insights from our Big Data specialist, grounding our analysis in the collective experience of various experts, user reviews, and hands-on work with both of these tools.

Pricing model & scalability

Power BI employs a tiered pricing model – every tier, from basic to premium, offers varying functionalities. Notably, Power BI offers a free version ideal for learning or individual projects, while Looker lacks a comparable complimentary offering.

Looker adopts a consumption-based approach. Instead of fixed rates, it calculates pricing based on data usage and number of users, ensuring businesses only pay for what they consume.

While Power BI’s tiered pricing model provides clear distinctions, making it easier for businesses to understand what they’re getting, its ‘Premium Per User’ offers flexibility to smaller teams needing advanced features without breaking the bank. Looker, conversely, is intriguing for businesses that cannot predict monthly BI engagement and prefer a model that scales with use.

Typically, Looker charges around $5,000 monthly for a group of standard 10 users. However, they offer customized pricing based on user needs. In contrast, Power BI provides a more budget-friendly alternative. Power BI Pro is priced at $10/month per user for self-service data visualization, while Power BI Premium comes in at $20/month per user or an overarching $4,955/month without user restrictions. However, your choice may depend on scaling models.

Power BI’s integration with Azure offers a scaling model that has predefined tiers. These tiers are designed for varied data loads, but transitioning between them may not be instantaneous. There might be scenarios where sudden spikes in data processing needs can result in performance bottlenecks if the tier isn’t adjusted in time. Looker, backed by Google Cloud, uses a more dynamic scaling approach. Due to its underlying cloud infrastructure, it can quickly provision additional resources in response to increased demand. This can be especially advantageous when the data load is unpredictable.

“For startups or small businesses with predictable BI needs, Power BI Pro or PPU might be more economical. However, larger enterprises or those with volatile usage patterns might find Looker’s consumption-based pricing beneficial in the long run.”

Deployment strategies

Looker is a 100% cloud-based platform, bringing forth the advantages of instant scalability and zero infrastructure. With Looker, there’s no need for companies to stress about physical servers or technical teams dedicated exclusively to its upkeep. From SMBs to large enterprises, the scalable nature of Looker’s infrastructure allows for unhindered growth. Additionally, the automatic updates that Looker rolls out mean that businesses always have the most up-to-date features without any downtime or significant manual intervention.

While Power BI does offer a cloud-based solution known as Power BI Service, it also comes with an on-premises version called Power BI Report Server. This gives organizations the flexibility to choose their deployment option based on their infrastructure, security, and scalability needs.

The Power BI Service is quick, automatically updated, and integrates well with other Microsoft products, giving it an edge for those already embedded in the Microsoft ecosystem. However, the on-premises version requires more maintenance and can be subjected to downtime during updates.

In terms of scalability, Power BI’s cloud version, just like Looker, is designed to scale seamlessly. But the on-premises deployment might face limitations depending on the organization’s IT resources. Additionally, while Looker primarily focuses on the cloud, Power BI offers both solutions, which might be an advantage for organizations that require more flexibility in their deployment strategy.

“While Looker demonstrates undeniable strengths in its cloud-first approach, Power BI’s flexibility in deployment options gives it a competitive edge. Power BI’s dual deployment strategies can cater to a broader range of organizational needs, from those who prefer the cloud to those who still rely on on-premises systems.”

Data integration & compatibility

Power BI, being a Microsoft offspring, is naturally optimized for Microsoft technologies such as Azure, Excel, and SharePoint. This makes it an ideal choice for enterprises deeply ingrained in the Microsoft infrastructure. However, its versatility doesn’t end there; Power BI also offers connectivity to a range of other services, including AWS, Google Cloud Platform, IBM, SAP, and more, catering to diverse data environments.

Looker, part of the Google Cloud portfolio, offers an expansive range of connectors. From databases to SaaS platforms, Looker’s flexibility is designed to be data-agnostic, ensuring that diverse data sources, even the less common ones, can be integrated.

“Choosing between Power BI and Looker requires a thorough understanding of your organization’s current data architecture and future scalability plans. Here’s a three-step guide:

Assess your ecosystem: If you’re predominantly using Microsoft tools and plan to continue doing so, Power BI will provide a more streamlined experience. If your organization uses a myriad of platforms or anticipates diversifying its tech stack, Looker offers broader compatibility.

ETL & data storage

Looker operates as an SQL query generator, pulling data directly from its associated databases. However, Looker does not offer inherent storage capabilities for the fetched data. In terms of ETL, Looker doesn’t have a dedicated mechanism but compensates slightly with its data modeling. This allows for more refined results like displaying transactions by specific time frames. Yet, this approach means the entire data table gets processed first.

Furthermore, Looker does employ a caching mechanism, storing retrieved data temporarily to speed up subsequent similar requests. The data stays in cache for a set period, such as an hour or a day, enhancing its retrieval speed. But, given Looker’s lack of comprehensive ETL processes and internal data storage, it seems at a slight disadvantage.

When evaluating BI tools, the ability to manipulate and customize data is crucial. Power Query is a feature within Power BI that facilitates data transformation, enabling users to extract and present data in the desired format. Looker, on the other hand, differentiates itself with its modeling layer, LookML. This language allows for deep customization and ensures uniformity, making it apt for businesses looking for a tailored experience without compromise.

“While Looker emphasizes data manipulation through code, Power Query offers a more visual data transformation experience. The choice hinges on available resources and preferences: some teams lean towards a visual interface, while others are more inclined to work directly with code.”

CI/CD process

Looker boasts innate integration with Git, auto-recording changes to its code in separate branches within the VCS. Post code reviews, these branches are merged and deployed. Thanks to Git’s merge conflict detection, team leads can streamline and unify code versions. Additionally, Looker supports versioning, a feature absent in Power BI. This version control further enhances Looker’s collaborative capabilities, setting it a notch higher in this competition.

On the contrary, Power BI’s workflow is distinct. Developers typically craft reports in Power BI Desktop, then publish to the Power BI Service. While most changes necessitate using the Desktop, some adjustments can be made directly in the Service, albeit with limitations. A significant limitation is that Power BI does not permit multiple individuals to work on the same report simultaneously. Collaborative efforts in Power BI can thus be a challenge. When multiple users edit a report, the risk of overwriting changes arises. Resolving conflicts often entails diving deep into the report’s XML structure to pinpoint differences.

“Having worked with both Looker and Power BI, I can attest to Looker’s collaborative features, thanks to its Git integration. It simplifies versioning and deployment. Power BI, while strong in data visualization, can sometimes pose challenges for team collaboration, especially with the Desktop and Service divide. For those deeply integrated into the Microsoft world, Power BI still has its merits. However, regarding teamwork and CI/CD efficiency, Looker stands out.”

Data visualization

Power BI excels with its user-centric interface designed for a broad spectrum of users, boasting intuitive drag-and-drop mechanics and an extensive library of templates. One of its standout features is the Q&A tool that swiftly transforms user queries into visual insights, making it invaluable for those needing immediate insights without a deep data background. Moreover, Power BI offers the possibility for users to employ custom visualizations created by the community or purchase more specialized ones. This open approach means that while there is a vast array of choices, there might be potential for inconsistencies or bugs from third-party visualizations.

Looker, in contrast, targets those with a deeper understanding of data. It provides granular control over visualization elements, ideal for experts who desire detailed adjustments. A distinguishing factor for Looker is its support for developing and publishing custom visualizations. Professionals can even craft restricted visualizations tailored for personal use, ensuring specificity without compromising the broader dashboard experience.

“When visualizing with Looker, there’s a necessity to adhere to certain layout standards, whereas Power BI offers unparalleled freedom in this domain. With Power BI, every element can be placed precisely where desired, granting more customization possibilities. Yet, this extensive personalization often comes with a price tag. Another thing to note: while harnessing community-made content in Power BI is feasible, it’s paramount to approach it with caution due to potential inconsistencies or bugs. On the whole, each tool caters to distinct needs and preferences, but both are formidable in their respective arenas.”

Security & compliance

Power BI and Looker prioritize data security through encryption in transit and at rest, robust authentication, role-based access control, data governance, auditing, and compliance certifications.

Power BI secures data in transit with SSL/TLS and at rest with AES-256 encryption. Its Azure Active Directory integration enhances security, and it offers data loss prevention (DLP) policies for compliance.

Looker uses standard encryption for data in transit and at rest. It shines with highly customizable role-based access control, centralized data governance, and advanced monitoring and alerts for proactive security.

“Power BI may be a leader in data security for organizations deeply integrated into the Microsoft ecosystem, offering Azure Active Directory integration and robust role-based access control (RBAC). It’s well-suited for enterprises with complex security needs and data loss prevention (DLP) requirements. Looker, however, shines when customization and flexibility are paramount. Its fine-grained RBAC and cross-platform compatibility make it an excellent choice for organizations with diverse data environments. Looker’s focus on centralized data governance and advanced monitoring and alerting can be advantageous for maintaining data security and addressing threats effectively.”

The ease of adoption can dictate the success of a BI tool. Power BI, with its intuitive interface, offers a gentle learning curve, especially for those familiar with other Microsoft products. Looker, while powerful, demands a steeper learning curve, especially when delving into LookML.

“For those familiar with Excel or SharePoint, diving into Power BI is relatively easy. The abundance of resources, tutorials, and forum discussions makes it easier to kickstart your journey — simply download the desktop version and get going. On the other hand, Looker, despite offering depth and granularity, has a slightly steeper entry point. Before diving in, one has to request a demo and navigate a bureaucratic layer, waiting for their team to make contact. This waiting period can be a deterrent for those eager to start immediately.”

Community & support

Power BI, as a Microsoft offering, boasts a vast support system complemented by a broad and active community. This expansive network ensures that users have access to a wealth of tutorials, forums, and official documentation. Additionally, Microsoft’s dedicated support channels for Power BI can be responsive and comprehensive. However, with such a sizable community, finding specific answers can sometimes be akin to searching for a needle in a haystack due to the sheer volume of information.

Looker, while having a smaller footprint in terms of community size, provides a tightly-knit group of enthusiasts that often delve into detailed discussions. While there might be fewer off-the-shelf solutions available, the support from Looker can be more personalized, given its scale. This intimacy means users can sometimes get direct, focused advice or solutions more rapidly.

“Power BI’s vast ecosystem, backed by Microsoft’s support infrastructure, ensures there’s always some form of assistance available. Yet, the challenge is discerning the most relevant from the plethora. Looker, with its more concentrated community, provides a depth of engagement, often accompanied by rapid and tailored support responses. Organizations should reflect on their needs: for those requiring extensive resources and a wide array of solutions, Power BI stands out. However, if your organization values in-depth, focused discussions and a more personalized support experience, Looker might be a good fit.”

Mobile experience

In an era of mobility, BI tools must adapt. Power BI offers a stellar mobile application, ensuring decision-makers are informed on the go.
