The phrase "a scalable alternative" is correct and usable in written English.
You can use it when discussing options or solutions that can be expanded or adapted to meet increasing demands or requirements.
Example: "Our new software offers a scalable alternative to traditional systems, allowing businesses to grow without limitations."
Alternatives: "a flexible option" or "an adaptable solution".
The failure of Mr. Bush to fully mobilize the most powerful innovation engine in the world — the U.S. economy — to produce a scalable alternative to oil has helped to fuel the rise of a collection of petro-authoritarian states — from Russia to Venezuela to Iran — that are reshaping global politics in their own image.
The networks on-chip (NoCs) emerged as a scalable alternative to address the increasing communication demands of such systems.
Recently, Coleman et al. reported high-shear mixing as a scalable alternative to sonication for the LPE of untreated graphite crystals.
Trinucleotide threading (TnT) represents a scalable alternative to conventional PCR amplification circumventing the above-mentioned problem [9].
By comparison, attempting to trace only a statistical (random or non-random) sample of the lost patients is feasible regardless of the size of the patient population and is thus a scalable alternative to census patient tracing approaches.
A balanced media to achieve pH control is a scalable alternative to expensive buffering, feedback acid/base control, or CO2 enrichment (which severely limits CO2 conversion efficiency).
36 Despite further experimentation, work-arounds, and attempts to deliver significant quantities of material, we were forced to abandon this organocatalytic approach to the trans-chlorocyclopropane unit and consider a more scalable alternative.
A seemingly inviting, scalable alternative is the use of immortalized brain endothelial cell lines.
Our results support the use of UniRef clusters as a comprehensive and scalable alternative to native sequence databases for similarity searches and reinforces its reliability for use in functional annotation.
A recent randomized controlled trial comparing on-line and on-site training programs in biostatistics and research ethics, for example, found marked and similar improvements among volunteer scientists, suggesting that on-line instruction may offer a cost-effective, scalable alternative to more resource-intensive face-to-face instructional programs [ 19].
Monolithic data centers are one way to address this, but also cloud computing such as Amazon's EC2/S3 can be used as a viable and scalable alternative for large-scale metagenome data analysis [ 140], provided that the data can be transferred to the cloud, and appropriate data security is guaranteed.
